CATEGORIES - OVERVIEW
AbeBooks maintains approximately 3,500 categories that are used by buyers browsing our Web site. These categories are shown in a tree structure with 50 top level categories.
The category list is a dynamic one and updates will be made available through our Web Services.
If you choose not to assign your listings to a category, our system will attempt to match them to the appropriate category. If you do assign listings to categories, we won't do any further matching. Each listing may be assigned to up to 10 categories.
Because these categories are defined by AbeBooks, they can't be edited or deleted.
