E-Books: Finding and Using Electronic Books

ProQuest Ebook Central

You can tell in IUCAT that an e-book is on the ProQuest (formerly ebrary) platform because the URL field will start with or ProQuest e-books can be single-user or multi-user. Multi-user titles, also called unlimited-user titles, can be viewed simultaneously by an unlimited number of users. You can tell that a title falls into this category if you see the circled text below that says “Unlimited-user title.”

If a ProQuest e-book is single-user, you will see the circled text below that says “1 copy.”


A patron is considered to be using a title if s/he downloads it or simply views it online.

Another status you might see is “Limited User Access (365 Uses Available).”  This means there can be approximately 365 uses per year, and there can be unlimited (within the 365 constraint) simultaneous users at a given time. 

Sometimes we buy more than one copy of a single-user title.  For example, if we buy two copies, then two users can access the e-book at the same time. 

The last copy of an ebook from ProQuest will not be able to be downloaded or checked out.  So, for example, if an e-book is single-user, it may not be downloaded. 3-user titles allow 2 downloads, and preserve online access for 1 user. Multiple-user titles may be downloaded.
