In all ebook collections, different ebooks have different permissions for the amount of users that can access them. The various permissions follow, and are indicated in the record for each ebook:
- Unlimited users: An unlimited number of people can read or download the ebook at one time.
- 1 User: Only one person can read the eBook at a time. Downloading of 1 user titles is not allowed. When an ebook is being read online, it is "checked out" for a period of time that typically expires after 30-60 minutes of inactivity. Tip: Instead of reading online, print or download a chapter at a time.
- 3 Users: Up to two people can download or up to three people can read the eBook at a time. One copy will be preserved for online access. Tip: Instead of checking the entire ebook out, print or download a chapter at a time.
DRM or Digital Rights Management
Some ebooks from EBSCO and ProQuest have Digital Rights Management or DRM, a technology used to limit the amount of content that can be printed, copied, and saved. These limitations vary by publisher and title.
