The Bookbinder is used to produce Manuscript, Tome, and Codex books. It costs 20 Pinewood Planks and 80 Stone to build and construction time is 5 minutes. Unique to this building is that it requires more time to produce its resources over time.
When a bookbinder has finished producing a Manuscript, Tome or Codex, a bouncing symbol will appear over the building. This indicates that the item is ready for collection.
