How can I tell how many other copies of what I posted on my bookshelf are out there?

How can I tell how many people want a particular book?

Thanks, I am new at this.

If a book posts to your bookshelf, then no one is waiting for it right now.  It'll stay on your bookshelf until someone requests it.

You can tell if something is on Wishlist by searching for the book and clicking on the title to get to the book details page.  It will say "members wishing" and the number of people.

To tell how many copies of something are in the system, add the books to your Reminder List.  Then, go to your Reminder List and it'll tell you how many copies there are currently listed.

Thanks for your help.
