Goodreads Librarians Group discussion

Could a kind librarian please help me with combining my two paperback versions of my book? It's all the same edition, but published on different dates. 1/1/16 is the paperback release date.

Thanks a million.

A Kindle edition was changed into a paperback. Have reverted that change. There are now a paperback, a Kindle and an ebook: https://www.goodreads.com/work/editio...
