i borrow cookery books from the public library; now, I can add them to my bookshelf, so that the recipes in them are discoverable in a search on my bookshelf, and then remove them when I return them, but it's one more thing to remember. Wouldn't it be good if there were a category of books one could add to one's bookshelf which could be set to remove themselves automatically at the end of the loan period? The loan period would need to be a variable the EYB user could alter, as different libraries have different loan periods - here in Britain typically three or four weeks.
