I was wondering if there could be a function for members to note a 'wish list' in their bookshelf/library, so that when they see a book they want to buy at a later date they can keep it in mind.
Perhaps it already exits?
I have thought of this as well. Seeing a book indexed, often tempts me to own it. I currently have a bookmark called "Wishlist" and add books to that, in lieu of a seperate list.
This has come up a few times in the past and it is on our (huge) to-do list. I can't give you a date but it will happen.
