After a couple of months of not playing Minecraft, due to work, a lot of updates has happened and the immense number new items is overwhelming for an old player. There was an update of strongholds which contains a library. Since the libraries don't have a purpose wouldn't it be nice if the bookshelves contains tomes of knowledge which has a couple recipes such as "A Blacksmith's Guide to Smithing" which contains recipes for creating tools and armor, "Vexillology: The Art of Flag-Making" I read somewhere you can make flags with the new updates(?), etc. How about making randomly generated ruins of old libraries? Or for villages to contain a town library?
For how bookshelves would contain books, found this deep within the forums:
