Bookshelves can be broken easily by hand, but can be broken faster by using a hatchet. In either case, they will drop three books when broken, allowing the reconstruction with an additional six wooden beams.
Crafting a bookshelf takes six wooden beams and three books.
Bookshelves can be used as fuel in furnaces, smelting one and a half item per bookshelf.
Bookshelves were in Venture since autumn 2015, but were impossible to obtain, albeit they were destroyed in explosions, though when broken dropped nothing. Brendan decided bookshelves should be obtained by crafting on January 29, 2016, and decided on the crafting recipe on July 23, 2016.
