I'm confused why the button choice for adding a book to "wish list" is not shown on all books.

I'm trying very hard to use the iphone app to organize my "haves" and "wishes." I'm having to resort to putting books I want into the "TBR" list.

Help?

If there is no WL button, that indicates that the book is available for ordering.  If you want to keep track of a particular book, I'd suggest using the Reminder button.  As far as I know, there is no limit like there is for wish listed books.

If the book is currently available then you cannot put it on your wish list so there is no button.  You could put them on your reminder list, it might be easier than the TBR

ETA:  Oops...looks like she beat me to it ;)

Thanks for the quick replies!

The only lists available in the iphone app are Wish List, Books I Have Read, To be Read, and My Bookshelf. 

You should tell the creator of the app that the Reminder option is missing. I think it is a paid app, so it really should be there.

Unfortunately, the iphone app developer only has access to a subset of the functionality of the full website. Hopefully the app get permission to grow in features.

I open PBS in Safari on the iPhone and use the drop down box to add books to my reminder list. I usually have to zoom in on the page to be able to click in the right place when viewing PBS on my phone, but it does work.
