I don't wnat to list books that have lots of copies ahead of it.  I can enter the book, and see if it's listed. I assume if it's listed, that means that at least one person has it on their bookshelf, ready to send.  Is there a way I can tell how many people have listed that book?

You can put the book on your reminder list. It will tell you how many copies are posted.

Current highly popular genres, authors, titles can move very quickly, even if there are already hundreds of copies posted.

Mine are all really obscure books.
 

Add the book to your reminder list. Viewing the list will show how many other copies are available. If you do this when posting the book you will know how many books are in front of yours, but there is no way subsequently to know where your book is as it moves up in the queue when other copies are requested. After placing books on your reminder list to see how many other copies are available, you'll probably want to remove them from the list so as not to clutter it up.

That's what I was looking for!

I had this same question!

Is there a way to move the book from your reminder list to your posted list? (trying to save time from adding it to my reminder than deleting it, then posting it)
