*Note: Not all things visibly update automatically. The best way to make sure a page or page container of any sort updates is to put it in a writing desk (or lectern/bookstand).
Agedata updates separately from the books, and will update automatically on any access.
Descriptive books may still show old pages until updated, but this is OK.
Pages in inventory update, but other items need to be put into a tile entity.
