If a book similar to yours is already in the database (e.g. same title but different edition), you can create a quick submission by auto-populating the submission form with information from the existing book. If you are familiar with submitting to Discogs, it's the same as the "Copy-to-draft" feature.
From that book page, click the dropdown menu next to ‘Edit this Book’ and select ‘Add one like this’:
Edit the existing data according to what’s on the release in front of you. You may also wish to delete some fields if they don’t apply to your edition of the book.
When you’re satisfied you’ve edited, removed and added all the information possible about your release, hit Submit.
Note: Images will not be auto-added when you create a ‘Add one like this’ submission. Please add images of your specific book for your submission.
