(It has been a couple of years since we participated in a DDA program with them.) Once you hit the trigger point, you automatically purchase the book. They also
<a href="https://www.proquest.com/products-services/related/Flexible-Access-Models.html">
have several other acquisitions models</a> if you decide they are a better fit.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D"><a href="https://about.jstor.org/books-jstor-demand-driven-acquisition/">JSTOR has an eBook DDA</a> that is based on the number of chapters viewed (6) or downloaded (4).

<p class="MsoNormal">Hello – I’d like to hear if there are any ebook DDA collections for which the triggers are a little more lenient than EBSCO’s. We use EBSCO DDA, and have had to turn it off now that we started using EBSCO EDS – because these ebooks turn
up at the top of the search, because they are ranked by date, and the DDA books are the newest. And it does appear that people are spending the 10 minutes evaluating these books that cause them to be triggered.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">One solution would be for us to remove all books from the most current 3 years or so from the DDA selectables. But I’m wondering if there are any DDA experiences that don’t purchase the book quite so readily.<o:p></o:p></p>
