Great Big Book of Everything



""Our friends need our help! Please turn to the time travel section of your Fireside Girls Handbook.""

The Great Big Book of Everything: The one-stop shop for all your plot needs. Need information about the super-power you've just been given? On the first page. Want to find the only way to kill the Big Bad? It has a detailed entry.

Whoever wrote this book must have damn-near infinite knowledge. It has all the facts you need and has them at the moment you need them! In fact, it seems like new information just appears in the book all the time, as the plot requires.

Every villain, even the really tiny ones, or the ones who have been sealed away so long that humans shouldn't have even heard of them, has an entry; every spell has a description; every fact and oddball bit of information in the whole universe is listed, if only you look hard enough. While this is a plausible plot point for a while, eventually you have to ask, who wrote this stuff? Did John Winchester really know all the information in his journal? If so, why are his sons following it to living monsters rather than ones he killed? Could the Halliwell ancestors really have known about the upper echelons of demon society? Creatures that never set foot on earth? All those cosmic entities that never show themselves to mortals are somehow in the book.

Effectively a Magical Database in paper format, it provides the information to the cast so that they can keep the plot moving without spending hours sifting through a library. Sure, some of it is an Ass Pull, but it helps us get to the ass-kicking.

This also appears in a lot of video games, usually as a "guidebook" or similar phrase. It always has everything you need to know to get out of any situation the programmers threw in there that you could conceivably be stuck on, even if they sometimes appear to be riddles. In this case, new information may even literally appear as the plot demands, the entry for each location, item, enemy or other piece of interest only readable after you have encountered it.

Compare with Library of Babel and Tomes of Prophecy and Fate. Contrast Blank Book. If it's evil, then it's a Tome of Eldritch Lore. Supertrope to Big Book of War. This trope is Do-Anything Robot in book form - and YOU do the Anything!

Anime and Manga

 * Yue's power in Mahou Sensei Negima is this, complete with an actual book that finds everything she needs. In Negima!?, Nodoka's "Armor" power has the same ability.
 * Material in the manga (vol. 16) reveals that it's actually tapping in a magical 'net, which can be both an advantage and a flaw: Information is always up-to-date, but you risk losing data "arbitrarily deemed of lesser importance"
 * On the other hand, she has no problem accessing highly classified information.
 * In Pokémon, Brock likes carrying around "Guide Books" in which he looks up vital information about tournament rules or opportunities to eat or shop. He also has a separate guidebook containing accurate details on female celebrities.
 * James uses a bunch of Pokemon cards in place of a Pokedex.
 * Tao, in the '80s toon The Mysterious Cities of Gold had an encyclopedia from the civilization that built the Seven Cities of Gold. Used more for plot exposition than Deus Ex Machina.
 * The Universe of the Four Gods books in Fushigi Yuugi.
 * Bokomon's Book of Knowledge in Digimon Frontier mostly fits this, although it doesn't seem to have data on things that have never existed before (including the final forms of the heroes and villain).
 * The Clair Bible in Slayers NEXT, or at least the manuscripts of it. The actual Clair Bible turned out to be something a little more complex.
 * The manuscripts handled this fairly realistically: most seem to be monographs, with little or no information on other subjects(and thus could easily be part of a massive library). The trope's slightly Deconstructed when we find an attempt to make a complete manuscript, though.
 * What Noah from Soul Eater is trying to do.

Comic Books

 * The Junior Woodchuck Guidebook in Disney's Uncle Scrooge comics (and subsequently in DuckTales (1987)) (and any other Duck story where it is needed. It is always there when a Junior Woodchuck needs it). A lengthy Don Rosa story-arc once revealed that it had been condensed from the entire content of the Great Library of Alexandria (with the lost history of South America and Asia added later). The library was a storehouse of ancient knowledge that was tragically lost to history through a series of disasters, culminating in a fire during the time of the Roman Empire.
 * The aspect of the Guide containing more text than could possibly fit into a single volume is usually explained by saying that there are actually numerous volumes that make up the complete Guide, just like any large encyclopedia. How they always happen to have exactly the volumes of the Guide applicable to the topic at hand, though, is handwaved.
 * One Donald Duck-magazine story had Donald getting annoyed at the book's seemingly infinite wisdom and asked the Woodchucks about who the author was. Cue panic as not even the top generals know. They then had to keep Donald tied up so he would not go to the newspaper with the information that "the Woodchucks follow advice that could as well be made up". In the end they do find the author's house, but decide that knowing who he is will ruin the magic behind the mystery. The shadowy author is then seen looking at them as they leave, contemplating that "if my book contains better knowledge than that, then I don't know it myself".
 * Interestingly, there's an occasion where the book was missing something - in "A Letter From Home", it doesn't list the order of the heads of the Knight Templar, much to their shock.
 * In another story it was discovered that it doesn't cover information that the Woodchucks are supposed to have learned in school, and will flat-out tell them it.
 * The Book of Oa of the Green Lanterns Corps. Later on we see the Book of Parallax of the Sinestro Corps and the Book of the Black, though these last two are more like a Tome of Eldritch Lore.
 * The Abstract in Runaways
 * Marvel Comic's Doctor Strange owns (or owned) the Book of the Vishanti, containing any spell or obscure tidbit of mystical information he might need. There is also its opposite The Darkhold. Each contains spells or information to perfectly counter something in the other.
 * Neil Gaiman's The Sandman series features Destiny of the Endless, who has a book chained to his arm that details everything that has ever happened, or ever will happen. The cover of this tome is made of the hide of a beast that never existed.
 * One appeared in Final Crisis: Superman Beyond, and was so heavy that Superman and Captain Marvel working together could barely lift it.
 * The Absorbacon in Silver Age Hawkman comics.

Fan Works

 * Parodied in the Kingdom Hearts fanfic Those Lacking Spines with the ever-handy guidebook which contains anything the protagonists need to know about a given world.
 * In the Total Drama Island fanfic Keepers of the Elements, there are The Elemental Books which contains all sorts of spells which each Keeper along the line either invented or improved upon.

Films

 * The Map of time in Time Bandits tells the protagonists where all the holes in the universe are, and drives the plot. Whenever the heroes get stuck they consult the map.
 * The "Sex Bible" from American Pie. Though, as the name suggests, its contents deal almost exclusively with sex positions. It's an interesting variation in that it's clearly been edited and updated by everyone it's been passed down to... meaning it's a Paper Wiki!
 * Mirror Mask both lampshades and plays this straight with A Really Useful Book. The book, a small pocket sized volume that appears to have some degree of sentience, consists of various pieces of advice written on its pages. In addition, the book always opens the relevant page.
 * More obviously lampshaded, yet (somehow) simultaneously played straighter, with a book Helena comes across earlier in the same library: The Complete History of Everything.
 * Tobin's Spirit Guide from Ghostbusters and its related media. In the second movie, Egon also references a book of occult history called Magicians, Martyrs, and Madmen.
 * Dana Carvey's Master of Disguise features a pop-up book which provides extremely specific information relating to any situation at hand on whichever page is randomly opened to.
 * Beetlejuice - Handbook for the Recently Deceased
 * The Book of Secrets from the second National Treasure movie. Filled with almost everything a conspiracy nut would love, and more on top of that. Most importantly the information the team is currently looking for, and, a hidden detail on page 47, which may come into play in the third film, if one ever comes out.
 * Max's dream journal from The Adventures of Sharkboy and Lavagirl.

Literature

 * The Sword of Truth series features Kolo's journal. First discovered in a hidden alcove in the Wizard's Keep in the third book, the journal provides information on dream walkers and the great war 3,000 years ago. In later books in the series, it seems even though the main characters have not one, but several, libraries of forbidden lore to consult, good ol' Kolo's scribblings are the first book they reference.
 * With a twist: The Fire-us Trilogy has the children, brains highly scrambled from the trauma of the virus, believing that a simple scrapbook is their Great Big Book of Everything, and that anything found in there will help them. The book's owner even forgets that she has pasted items inside it moments before, and claims that she has "found them" in the book.
 * The Atlas in The Keys to The Kingdom, which was written by the Architect for the Rightful Heir. Interestingly, the Atlas appears to be sentient, and it only shows the information its reader asks for. It also tailors its answer to what best suits the reader - when the protagonist first saw a strange, harmless looking creature, the Atlas saved his life with a succinct reply - 'Scoucher - run!'. In sufficiently hurried and splattered handwriting, no less. Quite a benevolent tome, the Atlas.
 * From the same author as the above, Garth Nix's Old Kingdom books feature a classic Great Big Book of Everything, called the Book of the Dead. It seems to have a finite (but very large) number of pages, but nobody's sure; they do know it contains everything one needs to know about Necromancy- but you can only let it fall open to the passage it wants to, can only turn as many pages at a time as you really need to, and won't remember what you read afterwards until you have to. Since this is not a unique artifact, it does raise the interesting question of where new copies come from. The only constant is the last page, which contains the Arc Words.
 * It's made clear that only a Necromancer can open the Book, and only an uncorrupted Charter Mage can close it. Since the Abhorsens are the only people to meet both criteria, it's likely they possess all the copies and may be responsible for keeping it up to date.
 * Two other books similar to the Book of the Dead are also shown. the less powerful "In the skin of a Lyon". the second is a cousin of the Book of the Dead called "The Book of Rememberance and Forgetting".
 * The Good Magician's Book in the Xanth series. Well, he is the Magician of Information. Somewhat lampshaded in one of the Xanth books - the plot of that book shows the Magician when young, compiling the Book in the first place. After writing the book, circumstances led him to decide to forget the co-author, and since she had such a large part in writing it, he forgot all about compiling the information himself. It somehow updates itself, though, since it still always has the answer to any question somebody might ask of the Good Magician. Though not always in a form that anybody else can understand.
 * The Grimmerie in Gregory Maguire's Wicked: The Life and Times of the Wicked Witch of the West. Its usefulness is somewhat lessened by the fact that it takes years of work to learn how to read the language the book is written in, or to be born with the ability to read it by virtue of plot-significant messed-up parentage, like Elphaba (the Witch).
 * The wizards' manuals in the Young Wizards universe. The fact that a manual contains any piece of information the wizard might want to look up is justified by the fact that they are created by the godlike Powers That Be. They even expand to contain more information on the kind of spells a particular wizard specializes in, so everyone's copy is different.
 * In the second novel Kit pulls out an embedded fold-out oceanographic map when he needs to know how deep the ocean is at a particular location.
 * Also playing a significant part in the first part of the series are the Naming Lights (AKA The Book of Night With Moon, containing the true descriptions of everything in the universe in the wizard's language, created by the Powers That Be) and it's shadow, The Book Which is Not Named (The Lone One's answer to the Naming Lights, containing twisted descriptions of all that exists).
 * The titular book from Neal Stephenson's Cryptonomicon, an all-encompassing bible of encryption, seems to have a near-magical status to the Allied cryptographers. It is updated as the war goes on, and by the present day, has been scanned into PDF format.
 * Also by Neal Stephenson, The Diamond Age has The Young Lady's Illustrated Primer which can teach martial arts, etiquette, computer programming and nanotech engineering. Probably a good few other useful things too. Not only does it contain seemingly all knowledge in the world, it can also get an extended knowledge and understanding of the reader's current situation and provides her with helpful advice and knowledge she'll need to handle dangerous situations. The Primer looks like a regular book, but it's actually an extremely advanced computer.
 * The Book of Magic in Piers Anthony's Apprentice Adept series contains everything there is to know about the various forms of magic on Phaze. When researching a particular spell, the entire book shifted to become a volume on that type magic.
 * Parodied in Good Omens with Agnes Nutter's prophecies; she saw the future with enough precision to make sure that the relevant prophecy was written on an index card chosen at random. However, most of her prophecies were too imprecisely worded to be easily understood, since she lived and died in the 17th century, before much of our modern technology was invented. So while she foresaw accurately, she did not always understand what she foresaw, leading to phrasings like "Orient's chariot" instead of "Japanese car". Some of these were easier to interpret than others.
 * Add to that, the vast majority of the prophecies were directly regarding her own descendants. So if you weren't a descendant, or closely interacting with one, you probably wouldn't find anything useful.
 * Dorothy Ann in The Magic School Bus always carried a book she called her "research" that conveniently had information about the day's subject matter.
 * Subverted in  The City of Dreaming Books by Walter Moers. The Big Bad gives the hero an old Grimoire and tells him that all the answers to his question are written on page 333.
 * This is a recasting of one of the tales of the Arabian Nights, "The Story of Yunan and The Sage Duban", one of the tales nested in the "Tale of the Fisherman and the Jinn". It also involves tricking someone into turning the pages in a book that has been poisoned.
 * Susan Cooper's The Dark Is Rising has The Book of Gramarye which gives the Old Ones everything they ever wanted to know about how to use their powers.
 * Harry Potter:
 * The Half-Blood Prince's copy of "Advanced Potion Making" contains information on a wide variety of topics, from recipes for better potions, to spells that can kill people.
 * Justified, it was Snape's old text-book which he improved with his personal notes, and while it's never stated how good is he at Potion Crafting compared to other experts in the topic, he seems to be quite knowledgeable in it, also said spell was unique and Snape seemed to take quite some pride for inventing it.
 * It's also quite remarkable how much plot-relevant information can be found in Hogwarts: A History.
 * In Nick Kyme's Warhammer 40,000 novel Salamander, the Salamanders consult the Tome of Fire, left by Vulkan, to determine the significance of finding an artifact from Vulkan's hand, and an unprecedented eruption on their home planet.
 * In Richard Bach's Illusions: The Adventures of a Reluctant Messiah, there is a book called "The Messiah's Handbook," which tends to open to a page with a relevant insight to the reader's current situation. Its most poignant insight: . This revelation shocks and distresses the main character.
 * William Hope Hodgson's Occult Detective Thomas Carnacki gets all his info on the supernatural from the fictional Sigsand Manuscript.
 * In The Gods of Pegana, Trogool (the Thing that is neither god nor beast) has a book that likewise contains everything that has and will happen. We are told that things happen because they are in the book.
 * Ella's incredibly helpful (and self-disguising) book in Ella Enchanted (moreso in the book than in the movie).
 * In the Oz series, Glinda is in possession of a Red Book that contains real-time updates about things that are happening in the world. The entire world, not just Oz, which enables her to check up on Dorothy, Betsy, Trot, or any of the other semi-real-world characters who jump back and forth between Oz and the USA. She can look up what goes on with any of the characters at any time, and she uses it as an early-warning system and as a plot starter.
 * The Book of Three from The Prydain Chronicles (also the name of the first book of the series) serves this purpose, being the chronicled Past, Present, and Future of Prydain. It was once referred to as the "Book of If" by Dallben, who mentioned that the prophecies in the book could easily have not occurred. Oh, and it has magic smiting powers to keep away the unworthy.
 * In The Girl Who Owned a City, Lisa is stated to be guided by a "great book," which gives her most of her ideas on how to run things her post-Apocalyptic kid enclave. The book is implied to be Atlas Shrugged.
 * The Book of Sand by Jorge Luis Borges is a short story about the titular book, so named because "neither sand nor this book has a beginning or end". The book is of unknown origin and has seemingly infinite pages, which are numbered non-consecutively with arbitrarily large numbers; one page number was mentioned as being a number raised to the ninth power. There is no way to find a particular page a second time (although it's not specified whether or not the protagonist tried using bookmarks). The actual content of the book's text is unknown, as it's written in an unknown language; but there are simple illustrations every 2000 pages, which the protagonist quickly fills up a notebook recording. It is impossible to find the first page or the last, as new pages seem to spring up between the cover and the reader's finger whenever he tries. When the protagonist becomes obsessed with the book and determines to be rid of it, he considers burning it, but is afraid that the burning of an infinite book would itself be infinite and would cover the world in smoke, so he instead decides to hide a leaf in a forest by tucking the Book away deep within the National Library.
 * Tom Holt's May Contain Traces of Magic features a Book of Human Knowledge which is mass-produced by the sorcerous corporation J.W. Wells and co. However, the book only shows the viewer what he or she needs to know at the time, not what that person specifically wants to look up, unless you know the cheat codes.
 * In James Stoddard's The High House, the Book of Forgotten Things. Just everything you've ever forgotten.
 * Coriakin, the ancient star-wizard from The Chronicles of Narnia, owns one.
 * In Elephants Cannot Dance, Piggie wants to teach her friend Gerald to dance, but that's something elephants just cannot do. He proves this to her by handing her a book titled "What Elephants Can Do."
 * The Hitchhiker's Guide to the Galaxy, which succeeded in anticipating both Wikipedia and eBook readers several decades before the invention of the Internet.
 * Also the Encyclopaedia Galactica, which is much more accurate than the Guide but much less popular.
 * Given the large number of quotations from it and references to it, H.P. Lovecraft's fictional Necronomicon is apparently a Great Big Book of Everything you really don't want to know.

Live-Action TV

 * The former trope namer Book of Shadows from Charmed. It becomes more interesting given the fact that it was written over centuries.
 * There are quite a couple of episodes, especially in later seasons, where the Monster of the Week is not referenced in the Book of Shadows, because it is too obscure to have been encountered before.
 * The book repeatedly turns to the right page on its own. It is implied that one of the ancestors turns the pages. It is also implied multiple times that the ancestors can add and remove notes at any time.
 * The witches themselves, as well as their protector angels, are seen writing new entries in the book in different episodes.
 * In multiple episodes, the witches lose their powers, every time resulting in wiping the Book of Shadows completely empty. The scripture returns once the witches regain their powers.
 * On other occasions, the sisters are turned evil. This changes the content of the book, which now lists many evil spells.
 * If the sisters start to attack each other, the symbol on the cover of the book changes and the sisters lose their powers. Also, the sisters can no longer read the book.
 * Also, the book is very much desired by the forces of evil, who often plot to steal it, with varying levels of success.
 * The book defends itself against anyone who isn't of the right alignment (good if the sisters are good).
 * In the last seasons, the sisters increasingly check out the library of the magic school instead, which seems to be much more comprehensive.
 * Careful watchers have noticed that the content of the book changes; for example, Phoebe at some points adds information on Cole, the human form of Balthasar - but the information is gone at later points, replaced by either blank pages or completely different information. This is actually the result of the prop and art department placing new or different pages into the book based on the episode. It's easier to open the book near the center of the book, so pages were often moved around. The actual prop had three posts to put in removable pages so new entries could always be added as needed.
 * The diary of John Winchester in Supernatural has been dubbed the Book of Shadows by the recappers at Television Without Pity, based on how often it has all the answers the brothers need.
 * This is true for the first two seasons, but Sam and Dean become much less dependent on John's journal during Seasons 3 and 4. They use Bobby's library as a resource more often now, and they have to search more to find information about the Monster of the Week. Then in "Weekend at Bobby's", his Lower Deck Episode, we find out what happens when he needs a certain book from a closed library; he simply breaks in and steals it.
 * The diary of Laura Palmer from Twin Peaks, which was Defictionalized as a companion book to the seres.
 * In the final season of Angel, Wesley gets access to a set of books which really do have all the information in the universe; however, they are magical (they can, on command, display the text of any book ever written), and their power becomes a plot point in one episode.
 * Power Rangers Mystic Force has a temperamental version in the Xenotome: Its pages are blank until it decides to show the Rangers something.
 * In the early days of Smallville, everything Clark and Chloe needed to know about the Freak of the Week could be found on either the Wall of Weird, or the past issues of the Torch. These days it's from the Daily Planet archives.
 * The Professor from Gilligan's Island has one, but instead of a single book, it's a Bag of Holding backpack that always had the right book on top.
 * The Book of Changes in Ghost Whisperer, well, changes every so often to include the latest vague supernatural prophesy. It's also a last-minute MacGuffin at the end of season four.
 * During their "shopping" episode (showing where they get all their stuff), the MythBusters have a book of knowledge filled with the usual things like conversion tables but also a lot of obscure information that would be important for their show. The Pocket Ref.
 * The archaeologist River Song's diary in Doctor Who, a diary of her adventures recorded on her own, combined with eyewitness accounts of the Doctor through the ages, as seen in "Closing Time".
 * One of many, many tropes the Intersect in Chuck embodies at one time or another. The Intersect is a massive database of secrets and information vital to national security, uploaded to the protagonist's head in the first episode, and accessed involuntarily whenever he needed to know something related to that week's plot. Later upgrades included such things as combat skills, all of which went to whoever had the Intersect at the time via Neural Implanting.

Tabletop Games

 * Mage: The Awakening has a book called "the Invisible Codex" which is able to contain whatever information the reader most requires at the time. This is because it is an Abyssal meme, and its granting information is a ploy to get the reader invested enough in it so that it can devour their soul.
 * Dungeons & Dragons
 * Forgotten Realms has Golden Skins of the World Serpent - an artifact made by one of Creator Races and more widely known as Nether Scrolls. It looks like 50 golden and platinum scrolls (there were two copies, thus 100 pages total), thematically divided into 5 equal sections that cover arcane themes from the basics of magic to creation of major artifacts - advanced topics require understanding prerequisites. The unusual part is that the scrolls change for the reader and as such contain practically infinite amount of magical knowledge: one could study them again and again and uncover more and more of such lore. Moreover, elves discovered that a set of scrolls can be transformed so that it provides lore of intrinsically elven magic that was introduced or developed millenia later and as such could neither be feasibly possessed nor meaningfully used by the artifact's creators; which in turn means it most likely either works as an analyzer of the magic Weave that adapts to the current user or is kept updated by the incumbent goddess of magic (which may be the same, since she is one with the Weave).
 * In Ravenloft, the lich-king Azalin owns a magic book that records the biographies of all of the sentient inhabitants of Darkon (Uncoincidentally, the very first biography the book recorded is of Azalin, which began writing the very moment he stepped into Castle Avernus for the very first time). Newcomers to Darkon eventually lose their memories of having ever lived elsewhere due to the book magically editing their memories concerning their origins. There are only two ways to recover or preserve a foreigner's memory, in that either Azalin or one of his enslaved scribes personally edits that particular entry, i.e., like writing "the ambassador from Nova Vaasa is not subject to Darkon's memory-eating," or by having the afflicted person leave Darkon. The primary problem with the latter is that such new natives never find a reason to ever leave Darkon...
 * Traveller : The AAB the Vilani Repository of Knowledge, a great big library of everything.
 * The official setting for Champions includes the Cryptonomicon, which contains "all the mystic knowledge of the pre-Atlantian ancient world". The "tome" is actually in the form of a puzzle box that must be studied and solved in order to gain its knowledge. Unfortunately, it is also a trap: the more the puzzle box is studied, the more the scholar's soul is warped until eventually he it converted into a slave of the Kings of Edom. A mystically powerful slave, true, but a slave nonetheless.

Theatre

 * creates one of these for Faustus.
 * The titular book in How To Succeed In Business Without Really Trying.

Video Games

 * In Paper Mario: The Thousand-Year Door, one of Mario's partners has a book with information and pictures of every enemy in the game. This even includes.
 * However, it does not have infinite knowledge; this is demonstrated when Goombella lampshades that it doesn't answer her real question: where all the hammers come from.
 * It doesn't have.
 * Super Paper Mario has the Dark Prognosticus, a book which has prophesied every event of the game. The villain, Count Bleck, has it, and often quotes directly from it, with the effect of narrating his own life.
 * Rosalina's Storybook from Super Mario Galaxy has elements of this, if the second game's ending has credence.
 * The Traveller's Tome in Okami even gives you information on hidden god powers - with a treasure chest popping out of nowhere to give you information on whatever new power you gain
 * Uncharted opens with the recovery of Sir Francis Drake's Lost Diary, by his remote descendant, Drake. The Diary then serves in this regard for adventures in both the Amazon Jungle and an uncharted island in the South Pacific... somehow, it always has the key for whatever puzzle stands in your way.
 * And for the ten-odd chapters where you don't have the diary, then you have either the map, or good ol' fashioned ingenuity.
 * The Book of Prophecy from Avalon Code. In addition to being able to learn anything on any character, item, or monster that you see in the game, it's where you draw all of your weapons. To get some of that information in the book in the first place, the target entity has to be smacked upside the head with it. Don't worry...they won't see or feel a thing.
 * Both Myth games feature the Total Codex, a biography on every person who will ever live. During the first game the narrator looks in it and reads about the Summoner, a man who will resurrect the Myrkridia and visit untold horrors upon the land. He closes the book fast.
 * In Valkyrie Profile, Lezard Valeth states that he found the Philosopher's Stone (this version granting all knowledge), but that people have to work to get any knowledge out of it. He later clarifies by saying that a more accurate description of the Philosopher's "Stone" is the "ten-billion page codex."
 * In Blaze Union, Nessiah's Spell Book, the Revelation of the Gods, is reputed to be one of these. Its all-inclusiveness is justified by the fact that its owner.
 * Kingdom of Loathing has an appearance by the Tome Of Tropes, which is all but explicitly TV Tropes in magical book form. Reading this particular trope page in it isn't advised, as it tends to make the book implode violently.
 * In Ultima, the Codex Of Ultimate Wisdom. Unfortunately, reading it is a bit tricky (the entire fourth game is spent finding the darn thing; in the fifth game, it is stored on a faraway volcanic island with guardians that only let you pass if you're on a Sacred Quest; in the sixth game, it still is, and your final quest is to send it back to the void).
 * The eponymous Elder Scrolls from The Elder Scrolls series. They exist partially outside of time and thus possess knowledge of things to come for those able to read them. They also possess various time related powers because of their unusual nature. They have a bit of Tome of Eldritch Lore flavor to them too, since ordinary mortals can't read them without suffering terrible consequences, the least of them being permanent blindness.
 * To a lesser extent, Hermaes Mora's Ohgma Infinium. When a player reads it, they immediately gain 5 levels in all stats of a chosen path. But then the book dissolves before the player is overwhelmed. But then with a prevalent bug, players can avoid the disintegration and go all the way to max level within 15 minutes.
 * The Logbook in the Metroid Prime series. Your Scan Visor can, within a few seconds, tell you nearly everything about anything, and while ultra-detailed analysis may be able to tell you most of it, you sometimes wonder: where does your Gunship learn the name of an inter-dimensional creature that no being off-planet has ever even heard of?
 * Histoire of Hyperdimension Neptunia is a recording of the history of Gamindustri, and soon knows everything about the world. The downside is she has to look up the information before she can use it, which can take anywhere from three days if she gets lucky to up to a month.

Webcomics

 * In Exiern the wizard Faden's magic encyclopedia is supposed to be one of these, in that you ask it a question and it brings up a passage that relates to your situation. Its specialty is delivering the information in the most insulting manner possible and seems to pick on protagonist Tiffany.
 * Goblins feature the Paladin's Handbook. Apparently full of good advice, but may have worked better if read before a described situation arises.

Web Original

 * In Zero Punctuation's review of Heavenly Sword, when Yahtzee questions the meaning of the word "twing-twang", his avatar is briefly seen looking it up in a book titled "Words That Exist".
 * The podcast Flat 29's Big Book of Everything purports to be this.

Western Animation

 * "The Book of KND" from Codename: Kids Next Door. Apparently when it is found by the first kid to fight against adults ever, it already has every information he needed from building tree-houses to building sophisticated kid weaponry.
 * "Tobin's Spirit Guide" from The Real Ghostbusters. In Extreme Ghostbusters, we find Egon has added to it.
 * The Filmations Ghostbusters team have a Ghostbusting Manual in the first episode, which details the features of Ghost Command, the equipment, and the Ghostbuggy. It is never used again.
 * The Great Book of Gummi in Adventures of the Gummi Bears.
 * The Golden Grimoire, which Eric (who's been temporarily infused with Dungeon Master's powers) once attempts to use to send himself and his friends back home in the Dungeons & Dragons TV series.
 * Also, in one of the choose-your-own-adventure books, Sheila (or better said, the reader) must help the good witch Agnes to recover her stolen spellbook. Said 'book contains, among other incantations, a very powerful spell that can be used to fight the dragon Tiamat . Obviously, you have to go through lots of crap for it, which includes going against Big Bad Venger alone
 * ♪Iiiiiiiiiittttttt's the great big book of everything, with everything inside / See the world around us, this book's a perfect guide♪ - In the Playhouse Disney show, Stanley.
 * In Phineas and Ferb, the Fireside Girls have a guidebook that goes far and beyond camping or selling cupcakes. There are instructions on how to fix a Time Machine or refuel a NASCAR racer or wrestle an alligator.
 * Danny Phantom has two: The book that details Fright Knight and his defeat in one episode and another, a Greek Mythology book that tells a Sadly Mythtaken version of Pandora's Box. All conveniently held by Sam.
 * In, Chuck Jones' 1942 Merrie Melodies short "The Dover Boys," villainous Dan Backslide consults a Handbook of Useful Information for "How Best to Remove Young Lady from Tree (Fig. 1)."
 * The book of rules in The Fairly OddParents, which describes the limitations on what wishes can be granted.
 * Mucha Lucha has the Code of Masked Wrestling, which even detailed what to do when you are tied up in the middle of three bad guys using their signature attacks against you.
 * The Hero's Enchiridion in Adventure Time.
 * In Dragon Tales, The Magic Story Book serves as both an anthology of stories and an all-purpose guide to Dragonland. Complete fiction and non-fiction in one text!
 * According to my research, Dorothy Ann on The Magic School Bus carries a book with answers to every possible scientific question. At least, answers sufficient for an elementary-school kid's needs.
 * The titular Book of Virtues in Adventures from the Book of Virtues.
 * ThunderCats (2011) has the "Book of Omens", a combination of science and sorcery.
 * In Winx Club, Faragonda gives the titular group a book that details every part of their newest transformation, Believix.
 * In Harvey Birdman, Attorney at Law, Birdgirl has a book for sidekicks that she uses when she is not sure what to do.

Multiple Media

 * The Encyclopedia Galactica from The Hitchhiker's Guide to the Galaxy metaseries, being the eponymous Guide's somewhat stuffier main competition. The Guide, however, is more popular because it's slightly cheaper and has the words "DON'T PANIC" inscribed on the cover in large, friendly letters. (The EG still pales in comparison to the Ultra-Complete Maximegalon Dictionary of Every Language Ever, modeled closely on a certain real world dictionary, which requires a fleet of lorries to transport even in miniaturized form.)

Real Life

 * Early attempt: Enquire Within Upon Everything, a Victorian domestic reference.
 * "Whether You Wish to Model a Flower in Wax; to Study the Rules of Etiquette; to Serve a Relish for Breakfast or Supper; to Plan a Dinner for a Large Party or a Small One; to Cure a Headache; to Make a Will; to Get Married; to Bury a Relative; Whatever You May Wish to Do, Make, or to Enjoy, Provided Your Desire has Relation to the Necessities of Domestic Life, I Hope You will not Fail to 'Enquire Within.'"—Editor.
 * Pocket Ref by Thomas J. Golver is about as close to this as you can find IRL. MythBusters approved!
 * Desk Ref by the same author is even more so.
 * Dr. Ankowitschs Kleines Universal-Handbuch, containing a large variety of practical and some of the rather bizarre points of information, from how to clean a feather boa to the break-down schematics of BMW Isetta 250-model's chassis. Sadly this book is apparently only available in Germany and Finland.
 * The 44th edition of the CRC Handbook of Chemistry and Physics is another candidate and expanded far beyond what the title suggested, unlike later editions.
 * Rutters were a combination of a downplayed version of this and Treasure Map (they were after all for the purpose of getting, well, treasure). They were a custom in Medieval times of Ship's Captains keeping almanacs including a series of charts usually with the harbors disproportionately enlarged (that is after all a place where you absolutely have to come closer to shore than needed to take landmarks). Other things include local navigational notes, commentary on customs and politics needed to get into the local market without Culture Clash, and regular business contacts. Some rutters were secrets of a family or merchant house and passed down as an inheiritance. Toward the end of the Middle Ages some printers started publishing more generic rutters for anyone traversing a given route.
 * There were overland versions of this. One famous one in American history is The Prairie Traveller which was a guidebook for migrants on the Oregon Trail.
 * The Talmud.
 * Does the Oxford English Dictionary count?
 * Another possible real-life influence on this trope: The Everyday Reference Library.
 * William Blackstone's Commentaries on the Laws of England.
 * The Other Wiki, which often seems like The Hitchhiker's Guide to the Galaxy of our universe.
 * The internet, duh.
 * The 1911 edition of the Encyclopedia Britannica was thought to be this when it was released, covering practically everything involving scientific and historic study known at a time when the world was seen as static and that it was possible to know everything. After 1911 things got...complicated.
 * This Very Wiki strives to be one. Compared to The Other Wiki, it is still in its infant stages, but, as There Is No Such Thing as Notability, we're definitely catching up.
