how to merge two identical editions

If a particular edition is listed twice, it is appropriate to merge the two entries into one. Please do not delete an edition of a book just because it does not have an ISBN. Some older books that members manually add will not have ISBNs. Please check carefully and err on the side of not deleting a book edition.

Note that merging two editions deletes the less popular edition and merges all reviews into the more popular edition. This is different from combining editions, which is where you can mark one version of a book as the same as another.

When you find a duplicate and you know which edition it was meant to be, this is how to merge that duplicate with the actual edition:

1. Separate the duplicate and its actual edition from any other editions of that book.
2. Combine them just with each other.
3. click 'delete this book' at the bottom of the edit book page. Note that this only works for books with less than 15 member reviews. It will merge with its actual edition because this is the most popular (only) other edition available in that combination.
4. Re-combine the actual edition with the other editions of the book.
