Dataset For Books Published By Genre Over Time

Hello, hoping to identify a dataset that shows the number of books published by year by genre (e.g., 100K fantasy books published in 2018 vs 90K in 2017), or another proxy for popularity (e.g., sales). Particularly indexed on the (1) Fantasy and (2) Romance genres.

I have tried a few angles:

Library Datasets – Seattle Public Library reports checkouts by year by title, however this seems to be the exception and other major libraries do not report this same data ISBNDB – Based on ‘database’ page, it does not appear to include genre in the dataset (closest is Dewey decimal for select rows)

Fine with leveraging a paid database / report to improve approachability of the dataset.

Thank you for any guidance you can provide.
