Methodology
- Catalogue: every published book on Readark on the snapshot date, after removing off-topic titles (young adult, non-romance, non-book products) and merging duplicate editions of the same book.
- Spice and darkness: 1–5 ratings produced with machine assistance and editorial review, as described on How We Rate. They are directional, not the result of an editor reading every book.
- Content warnings: not every book is tagged yet, so warning shares are calculated among books that carry at least one warning.
- Amazon ranks: Best Sellers Rank data from Amazon’s catalogue, refreshed monthly. “Top-100” means the title held a rank of 100 or better in at least one Amazon category.
- Series: from Amazon catalogue series data and series numbering in book titles.
