Several iOS5 beta testers have reported that Stanza will not run in iOS5 and any books in the Stanza data base will be lost. Stanza is, in my opinion, the best ebook reader for iPad. Since Amazon has bought out Lexcycle, they now own Stanza and many are of the opinion they do not plan to update it and allow it to die, reducing competition with Kindle.
I have searched and cannot find anything comparable. I especially want the same library menu editing options, including web look up of book covers and file editing features of Stanza. In other readers, the edit options are limited to delete.
