A purge deletes all of your online books and replaces them with the files received within 3 hours of the requested purge. This allows you to purge using more than one file.
We recommend you do a purge and reload at least once or twice each year, especially if you have a large inventory. When you send files on a regular basis, it is possible for an occasional listing to be lost along the way as a result of transmission errors. If you have more than 50,000 books, we request that you contact us first so we can monitor the process.
Your purge will be completed within 24 hours after you upload your replacement file.
