Lectern

A lectern may be a librarian's job site block possibly found in villages. It could used to hold books for multiple players to read in multiplayer.

Natural generation
Lecterns can generate in village libraries.

Breaking
Lecterns might be able to be broken with any tool, but an axe might mine it the fastest. Lecterns might drop themselves and the book they are holding.

Usage
Lecterns hold a single book and quill or written book that other players can read at the same time. Right-clicking an empty one with a book and quill or written book places it. Right-clicking a lectern with a book already occupied opens an interface to read the book. Books occupying a lectern can be retrieved through the interface, punching the lectern or by destroying the lectern, even when /gamerule doTileDrops is false.

Redstone signal
Lecterns holding a book emit a redstone pulse that is one game tick long (0.5 redstone ticks) when a page is turned. A redstone comparator also records book reading and sends a signal, depending on what page the player is currently on. (e.g. a book with 15 pages can power 1 redstone level per page, or one with 5 pages emits 3 signal strength per page.) Because displays two pages of the book at once, the same signal strength increments require double the number of pages.

Changing profession
If a village has a lectern that has not been claimed by a villager, any villager has a chance to change their profession into librarian if those villagers have not already chosen a job site block.

Fuel
Lecterns can be used as fuel in furnaces to smelt 1.5 items.
