Cataloging Services – Anyone Used Penguin Publication?

[Maggnuson]

When I self-published my poetry collection, getting it properly cataloged felt overwhelming. Penguin was on my list too, but I ended up using Blueberry-AI to handle the metadata and classification. It helped clean up the ISBN details and made sure everything showed up correctly in online searches. My book actually popped up on a local indie shop’s site, which was a cool surprise.
