Java Edition:Infinite Box Book
In the April Fools' snapshot 20w14∞, the box of infinite books could make written books with an obfuscated author and impossible titles.
Obtaining
To obtain the book, the player must first obtain a box of infinite books. There are many dimensions that include them, but the best dimension is the library dimension, which contains shelves of them from the bottom to the top of the world. This dimension includes exactly one bookshelf for each possible book that can be generated. These shelves can be mined and picked up to be placed in other locations, although this is optional. Right clicking the box of infinite books block will cause it to drop a book as an item entity. The box of infinite books will not generate a book if it is on the corner of two chunk borders, if it is on the north/south chunk border and is facing east/west, or if it is on the east/west chunk border and is facing north/south.
Copies
Written books may be copied in 13w36a (a 1.7.2 snapshot) and above by crafting them with a book and quill. 14w05a (a 1.8 snapshot) added the generation tag, which increases by one each time the book is copied. The three variants that can be created are "Original", "Copy", and "Copy of a Copy". Books that are a copy of a copy cannot be copied further. All books created before this point and newly signed books will be considered original.
Book Info
The author of the book is §kUniverse itself, which appears as obfuscated text in game. The title of the book is in the format of <chunk x position>/<chunk z position>/<block rotation>/<chunk offset>/<y position>. The chunk offset is calculated as either 15 minus the block's x position in the chunk if it is facing north, the block's x position in the chunk if it is facing south, 15 minus the block's z position in the chunk if it is facing east, or the block's z position in the chunk if it is facing west.
This title can reach a maximum of 26 characters, which is longer than the normal maximum of a book title of 16 in this version. To get the maximum character length in the title, each factor must be maximized. The chunk position must be negative and at least -1,000,000 for both the x and z. Rotation doesn't matter. The chunk offset must at least be 10. Height must be at least 100. The most difficult of these is the chunk position because it requires the player to go to at least the coordinates -16,000,000 and -16,000,000 (~53% of the way to the world border). Inversely, the minimum length of the book title is 9 characters by minimizing all of these attributes. Each chunk can produce 14,336 unique books, and there are 14,062,485,000,004 valid chunk positions within the world border, meaning there are 201,599,784,960,057,344 possible titles.
The inside of the book will be 16 pages of random lowercase letters, commas, periods, spaces, and new line control characters, totaling 30 unique characters. Each page will contain 128 of these characters. The text is not purely random, as it is derived from the book's title. This means that books generated from the same shelf will have the same contents. These books may also have either state of the resolved tag, as they are generated unresolved. Opening the book changes the tag of the stack opened to 1b (true). Resolved books will not stack with unresolved books.
