Nielsen BookScan data is accessed via a series of apps built in Power BI. You can find links to the apps below; you will only be able to open those to which your organisation currently subscribes, and only after your email address has been granted access by Nielsen BookData. If you have any questions or issues, please contact your BookScan account manager. After you have opened each app for the first time, then you can go here to access PowerBI:  BookScan PowerBI
