combining two goodreads files

[Stephen]

As a recent librarian I have this question: there are two files on gdrds for the 1984 hardcover edition of The Short Life of Sophie Scholl, published by Harper and Row. Today I added a cover image to each one and made some other small corrections. One had an incorrect isbn. I should have accepted that it not be saved, but instead made the mistake of removing the isbn and saving the edition. Either the two files should be combined or the one with no isbn in the designated space should be trashed. Could someone please advise what course to take? Thanks a lot,
Stephen

ISBN 0060263032 (ISBN13 9780060263034) is the valid ISBN of a Library Binding edition, so both editions can stay. I reversed the change and corrected the edition data accordingly.

Thanks very much.
