The Bookcase holds up to 16 books and shows visually where the books sits in the inventory. Also works with enchantment tables. The books are counted and 8 books count as 1 vanila bookshelf. So a full bookcase counts as 2 vanilla bookshelves.
The bookcase also comes in the 6 different vanilla woods and in a framed block version which can be used with the Furniture Paneler to make it look like any solid block.
The bookcase can also be shifted forward to sit on the front half of the block.
Player can place books directly in the Bookcase by right clicking with an accepted book. Right clicking the Bookcase without an accepted book OR if the Bookcase is full will open the GUI. Sneak clicking with an empty hand will pull a book off the Bookcase. Books will add/subtract from the slot the player is aiming at.
The bookcase can also emit a redstone signal when the item Redstone: Volume 1 is placed in the inventory. The slot the book is placed in determines the strength of the redstone output signal. The first slot does not emit any redstone. The second slot emits a strength of 1, the third slot emits a strength of 2 and so on up to the last slot which emits a full redstone strength of 15.
To shift the bookcase forward to the front of the block, right click the bookcase with either the screw gun or the hand drill. Sneak clicking with the screw gun or hand drill will rotate the block.
This block can be made from any of the 6 different vanilla woods or from framing sheets and framing boards (replace planks with sheet and slabs with boards) and will look like the wood that is used.
Look for these options in Minecraft folder under config/BiblioCraft.cfg
First there is an option to allow blank books. By default, the bookcase does not accept blank books.
# Should blank books be allowed on Bookcases? (true or false) B:AllowEmptyBooks=false
There is also an option to add additional types of books to the bookcase if one is not supported.
# These are the keywords that are compared against the item names to determine if the item can be placed on a Bookcase. Add more keywords if needed. S:AllowedBooks=book, map, journal, plan, thaumonomicon, necronomicon, lexicon, print, notes, spell, library, tome, encyclopedia
*Made some tweaks to creative mode bookcase item appearance so not as easy to confuse with normal bookcases
*Added Framed block version of Bookcase
*Added creative mode only bookcases that are randomly filled with random books (books such as those generated by the typewriter)
*Bookcases now accept the new Thaumcraft tome of Crimson Rites by default
*Fixed a bug that allowed wood planks to be placed on bookcases.
*New Mechanic: Bookcases can be adjusted to sit on either the front or back of a block by right clicking with the screw gun or the hand drill on a bookcase.
*Added enchantment particles to bookcases if a enchantment table is near and the bookcase has books.
*Redstone now propagates through the block behind the bookcase and display case. Also both blocks no longer emit a redstone signal from the front side.
* New Feature: Bookcases can emit a redstone signal of any strengh 0-15 depending on where the redstone book is placed on the shelf. Top left slot is 0, bottom right is 15. Could use this with comparators to create complex locks. 3 book cases alone would give a total of 4096 possible combinations.
* New Feature : Bookcases work with enchanting tables now. The number of books on the bookcases are counted and every 8 books is the equivalent of 1 vanilla bookshelf. So a full bookcases is equal to 2 vanilla bookshelves. The books do not have to be on the same shelf or even in the same bookcase for that matter, every book is counted.
* Added support for Tinkers Construct books on the bookcases.
*Tweaked Bookcase – Now the player can add and remove books from any slot on the bookcase by looking at that slot. The books are also rendered in whatever slot they are placed in. This makes the combination of the reading glasses and redstone book much fun. However, upon upgrading from a previous version, all current bookcases will appear empty, this is only visual, no books will be lost. The player must only change the inventory of the bookcase to restore rendering of the books. Simply open the GUI, pick up a book and place it back and the books will then show up on the shelf again.
*Added the Redstone Book and support for redstone emission.
* Upgraded Bookcase interactions: Player can place books directly in the Bookcase by right clicking with an accepted book. Right clicking the Bookcase without an accepted book OR if the Bookcase is full will open the GUI. Sneak clicking with an empty hand will pull a book off the Bookcase. Books will add/subtract from the top or bottom shelf depending on what shelf the player is aimed at.
