Is there a way to arrange the WL by date of release? I would like mine organized in that way since I have the majority of them that are not released yet. The only way I can find to arrange by date is by the date you added to WL  

You only have three ways of sorting, author/title/WL date - but that is the date you put it on your WL.   It is a good idea - send it on to PBS - maybe they will put it on the list of improvements. 

What about tagging them and then search for that tag??? 

eta:  you could also download them into excel and then sort by date???

just ideas.

Can't you export your WL and resort it?  I've hear of folks putting it into a database program.

The download only exports the title, author, isbn-10, and isbn-13, so you'd have to manually enter the dates to sort by release date.

Thanks for the ideas. I may have to try tagging them. I will suggest to PBS as well.

If you put a note on the book, you can see the note while you are looking at your WL.  Just hover over the cover image.  I know I mark which books are at my library with a note.  But it won't sort notes by release dates.
