If I go to https://en.wikibooks.org/wiki/Special:Book create a collection, add some pages and then try to save it under the same name of an existing collection I get a warning about that: ------------------------------------------------------------------------------ A page with the name Wikibooks:Collections/Acoustics already exists. Do you want it to be replaced with your collection? ------------------------------------------------------------------------------ but there should be a diff somewhere, so I can decide what to do.
