I can't seem to figure it out, maybe someone can help me out with it. I just want to know how to put them on my wishlist. Thanks so much.

There's a whole section on th Wish List in the Help Center.  Try this link 

How do I add a book to my Wish List?

Wait-not the link I wanted...be right back...

Well, ok it was the link I wanted, but you probably want the whole section, so....Click on the Gray Help Center tab, then Click on Browse Help Center Docs, then about 1/2 way down the list on the left side Click on "Using the PBS Wish List"  That has all the info. Although what you're probably looking for is this:

• Adding a Book to your Wish List:
  • Click on any listing for a book that is currently unavailable in the database. read about how to find books in the PBS database here.

• There is a limit of 200 items on each Wish List.

Hope this helps  :  )

Ok, for some reason my post came up blank... well a link was posted so that should help, sorry!

Look up the book you want.  If it's posted in the system but you don't want to order it right now then you have to add it to your reminder list.  If it's not in the system you just click on wish list and it will add the book.  You can only have 200 books on WL.
