When you find an e-book in the catalog, you will see one of three access terms: Single User Access, Multiple User Access, and Unlimited User Access.
- Single User Access = the book can be used by one person at a time
- Multiple User Access = the book can be used by more than one person at a time, but there is a limit to the number of simultaneous users
- Unlimited User Access = the book can be used by any number of persons at the same time
If you cannot access an e-book that is Single or Multiple User Access, it means that the book is already in use by the maximum number of users and is not available. Wait 12 hours and try again.
E-books can have many different types of licenses, so in some cases downloading an e-book to a personal device may not be allowed, although reading it online (in a browser) is usually an option.* In some cases, you may only have 5-minutes to browse the book before having to request access, and there may be a delay before a librarian can approve your request.
Similar restrictions, and often even more limiting ones, are common for printing pages and after closing your browser.
*If you encounter an e-book that is not available for online reading or that is not performing as expected, please go to the Library Services Desk in Willis Library, send an e-mail to AskUs@unt.edu or visit https://library.unt.edu/ask-us to report the problem. The library relies on customers to report problems so that the staff can fix them.
