How come only some books have the option to click WISH to add a book to my wish list?  How do I add books to my wish list if the WISH button is not there?

If there is no wish button it means that the book is actually available in FIFO and you could order it right away.  You can put it on your RL if you want to hold off or wait if you don't have credits.

Linda, thanks for the calrification. Is there a RL button?  Or is that the same thing as BTR (books to read) which seems to me that it puts it on your shelf like you already have it? help!  Sorry, I am new ;)

OK, I think I have it figured out now!  REMINDER list...not reading list!  thanks ;)
