E-book Access Question: Sudden Loss of Full-Text

QUESTION: I was able to access an e-book recently, but now I can only get to the table of contents. What happened?

The library is participating in a PDA (Patron Driven Acquisition) purchase program with some publishers, including R2 e-books. These books can be found on our e-books page and in our catalog. They are fully accessible until they have been used a certain number of times. Once that threshold has been reached, users can no longer access the full-text of the book–only the table of contents. The library then decides if it can purchase the e-book. Our goal is to make sure the library is purchasing resources that are getting used and are important to our users.

QUESTION: How can I tell if an e-book has been “triggered?”

If you mouseover (hover over) the table of contents link, a message will pop up saying this e-book is being considered for purchase (see image). If you would like to inquire about the status of a PDA e-book, or have other questions, please fill out this form: http://hslibrary.ucdenver.edu/databases?q=databases/problem-report
