 * Hi
    I’m sorry for that. This plugin is giving way to much problems. I thought
   google books would be a easy solution, but the api is very restricted.
 * Have you tried the similar plugin Google Bookshelves?
 * I’m probably going to stop development soon. Got no choice as my knowledge is
   limited.

 * Remove the whitespace before the <?php and after the the ?> in my-google-books-
   library.php. That eliminated the “headers already sent” error for me.
