Hmmm -- okay. The code in the WordPress plugin is explicitly removing them with the comment "13-digit ISBNs often have one, but not used by Open Library" (link to the current HEAD of trunk):
http://plugins.trac.wordpress.org/browser/openbook-book-data/trunk/libraries/openbook_openlibrary.php?rev=307486#L46 I can't remember if I used dashes when I entered the new editions; I think I did because that is what I copied-and-pasted from the O'Reilly catalog page. Is the problem is that there is no normalization of ISBNs happening in the Open Library index? When using the API, is it recommended to use dashes in ISBNs or not?
