Your ePUB file needs to be stored on a special storage location to be available for social DRM and distribution.
When submitting the ePub file you have two choices:
- Uploading with this form. After uploading the file it is stored in the ProBooks system, protected so it can only be read or copied by the admin of the system.
- Sending ProBooks a link to the ePub file, for example a Dropbox link.
Within 48 hours after submitting, the file will be transferred to the special location for social DRM.
