Other way around. Open Library is part of the internet archive. Given it’s also vastly superior in quality and has tools to maintain and administrate the data, I very much prefer it over alternative offerings. If Bookwyrm at least had a curation/maintainence team or support group or something, and not everyone could just nilly-willy add duplicates of existing entries, then I could see more use for it.

But like others have said, it’s also a bit of a different use case. If you want to pull data, definitely do it from OL. They’re the same source Bookwyrm uses for its main data import, after all.
