You might want to clarify that this does not search 28M books, it searches metadata for 28M books. Very different.

I notice many titles did not have authors. I spot checked this one: https://openlibrary.org/books/OL25434821M/Still_Star-Crossed

This title has no author in the search results, but does have one on the linked page. Perhaps an import issue.

Edit: Forgot to say "This is awesome. Particularly for 12 hours work!"
