I've gotten through WotC's D&D books and minis. I've done d20 Modern. I'm currently working on Star Wars books and minis. After that is the long, slow slog through the novels.
The goal is to do publication info, coverns, product blurbs, product review, a listing of the book's major content, and general documentation about the work. None of this is stuff that should be problematic, but it is stuff that a player or collector would want to know.
