The Category Codes are used by retailers, libraries and subscription services to ensure that your eBook is listed on the correct ‘virtual’ bookshelves. You can select up to three BISAC codes from this list (required in all cases) and one BIC code from this list (only required if you are listing with Gardners or we are allocating you an ISBN). Take some time to explore the different categories as there are many to choose from. Metadata And Book Info Form Total 1 Votes 0 1 Tell us how can we improve this post?
