Question about ACEs

[Michele]

The Librarians Manual has very good instructions https://help.goodreads.com/s/article/... on what to do if a new ACE was published earlier than the current one, and what to do if a new ACE was published later than the current one, but what does one do when the two publication dates for the two different covers are identical?

See here https://www.goodreads.com/book/show/1... and here https://www.penguinrandomhouse.com/bo...

Both have same ISBN and same publication date.

[Renske]

If two editions are published on the same date, the edition first added with the ISBN keeps it.

But sometimes an edition gets a new cover, but the publication date isn't changed. With your example it is quite possible it is a more recent change.

Sometimes Amazon can help with this. If one of the covers is currently listed on Amazon (provided it is an edition sold by Amazon itself, not a third-party vendor), that is considered the most recent one.

[Michele]

The brown/white cover is listed on Amazon https://www.amazon.com/Elmer-Gantry-S... and (as linked above) is also listed on the Signet Classics page as their current title. That all seems to indicate that it is indeed the most current. Thank you!
