I'm a librarian who loves anime, manga, and reading a wide variety of genres.
I just noticed that BookLikes has set things up so that the "add to bookshelf" popup has a green "BookLikes Author" link if the author is on BookLikes. Except I'm not sure this change (?) carried over to books already on shelves, or carried over to all editions, because the edition of Derrolyn Anderson's The Athena Effect that I originally had on my shelves did not have a "BookLikes Author" link. This bothered me, so I removed the book and then added it again.
If this happened due to BookLikes "every edition is its own island" problem, it's one more reason why I can't wait for them to combine editions somehow.
