Cloning a record can be a quick way of adding multiple variants of the same record to your list, or a quick shortcut when you see someone has the same record you want to add. To clone a record, find the record you wish to clone on yours or anyone elses list. Click on the album name. At the top there should be a tab that says "Clone", click this link. This will take you to a screen that looks just like the "Add a Record" screen except that all the fields are already filled in. The album name will be set to "clone of ..." to confirm you are in fact editing a clone and not the original. Remove the "clone of" section from the album name and alter any other fields you wish. Click submit when you are done and you have now cloned a record.
This should making adding multiple variants less monotonous while also adding a little shortcut for you just don't feel like retyping things.
