E-books: Terminology for students & faculty

A resource for information about E-books at USC Libraries.

eBooks are not created equal!

The Libraries purchases eBooks from multiple vendors, which means that users must become comfortable with slightly different formats, platforms, and different terminology. 

Single-user, SUPO: These indicate that only one user may access the book at a time. For this reason, the Libraries does not allow downloading of the book. For faculty, please note if the book you are assigning is a single user book. This will mean that only one student at a time may access the book.

3-user: This indicates that only three users may access the book at a time. For faculty, please note if the book you are assigning is a 3-user book. This will mean that only three students at a time may access the book.

Multi-user, MUPO: These indicate that multiple users may access the book at a time. Depending on the publisher, this number can vary.

Non-current, unlimited: These indicate that unlimited users may access the book at the same time. This is an ideal status, but not all publishers allow titles to be accessed this way.

Where do I find information about the number of users who can access an ebook?

When a user lands on the eBook page, there is always an indication of the type of book USC users can access. Because this is a single user book, it is unavailable for download.
