The "Subjects" category in your Title Information comes directly from Booksource's Collection Development team. Our experts work directly with over 150 publishers to select the best titles on the market and manually verify all interest levels, reading levels, subject tags, and other title information. 


Each book that is Booksource Verified, has been handpicked by our Collection Development team of experts. Our team selects each title and creates all Booksource Collections based on a range of criteria including reading level, interest level, subject, and content. Our experts work to manually ensure that the data we maintain on titles is up-to-date, accurate, and specific.

The "Subjects" category of your titles has been manually verified by our experts and narrowed down to the most specific, correct, and official information. You can even search your library by subjects just like you would with title or author information.


If you have additional categories you would like to tag your books with, you can always use the custom Genre field
