EBA: Evidence Based Acquisitions: Start

This guide describes the Evidence-Based Acquisition (EBA) subscriptions available at the CMU Libraries and how to access them.

What are EBAs and how will they work?

Evidence-Based Acquisitions enable us to evaluate and supply ebooks based on the needs of the library.  It is a hybrid model combining patron driven and package purchasing.

At the end of each EBA 12 month subscription term, a report will be sent out to the liaisons with title, cost, purchasing, usage, and other miscellaneous information collected during the EBA subscription period.  From that report, the titles with the most usage will be purchased.  Liaisons, however, also have the option to contact the Head of LTTS with any title they would like to purchase in perpetuity, regardless of usage, and it will be purchased.

How do I determine if we have access to a book through an EBA?

First search the library catalog.  If the title isn't listed there, check the individual EBAs with the links listed to the left.  You can also check in Gobi.

When searching Gobi, how do I determine if we already have access through an EBA?

When searching in Gobi, look at the right side of the screen to see if we have access through an EBA.  The right panel will indicate when it has been added to a library based evidence based collection.  

Can all EBA collections be seen in Gobi?

Cambridge University Press, Wiley, and Taylor & Francis are represented in Gobi and will be indicated in the right panel when we have access through their EBA collection.  

Is access guaranteed through an EBA?

Books accessed through an EBA are leased rather than purchased.  Because of this, some titles may be added or occasionally dropped during a subscription period.  At the end of the subscription, we will purchase the most used titles for our permanent collection.

Should I firm order a title that we have access to through an EBA?

It is best to wait until the subscription period ends and then the most used titles will be purchased at that point.  If you want to ensure a title gets purchased, you can send that title to Kim directly and she will order it at the end of the current subscription.  

Are all EBA titles listed in the catalog?

Most will be listed in the catalog.  Because new titles are added, or less commonly, removed periodically, the catalog may not indicate all titles in the collection at all times.  But most of them will be represented there.  It is recommended to search on the publisher platform if you wish to review the most up-to-date content.

How may people can access EBA collection ebooks at one time?

Access to all ebooks in the EBA collections is unlimited.

Are all titles from each publisher included in their EBA collection?

No.  The contents of the collections are determined by the publishers and can change for various reasons.   

Can ebooks be downloaded?

In most cases, full book PDFs are available for download.
