ALCTS e-Forum: Patron Driven Acquisitions/Demand Driven Acquisitions (PDA/DDA): The Good, the Bad, and the Ugly

August 5-6, 2015


Moderated by John Sandstrom and Samantha Rich


Please join us for an e-forum discussion. It’s free and open to everyone!

Registration information is at the end of the message.


Each day, discussion begins and ends at:

Pacific: 7 a.m. – 3 p.m.

Mountain: 8 a.m. – 4 p.m.

Central: 9 a.m. – 5 p.m.

Eastern: 10 a.m. – 6 p.m.


While PDA/DDA programs are not new, they are still developing and there is a lot of curiosity about them on the part of librarians and libraries that have not used them before.  We hope that this e-forum will provide a platform for current PDA/DDA users to share their experiences and non-user to ask their questions.  The following prompts will serve as discussion starters:

  • Which should we use?  Profiles or Collections?

  • How does PDA/DDA work with Discovery?

  • What is your experience with mediated vs unmediated purchasing?

  • Sharing General Concerns and Experiences

  • How do you assess your PDA program?



John Sandstrom is currently an Associate Professor and Acquisitions Librarian at New Mexico State University (NMSU) after having roamed through Academic, Public, Government, and Special libraries as well as a stint working for Baker and Taylor.  As Acquisitions Librarian he worked on the implementation and assessment of a PDA/DDA pilot project at NMSU and is overseeing a major expansion of the program in the next academic year.


Samantha Rich is the Assessment & Data Management Librarian at NMSU. She collaborated with John on the assessment of the PDA pilot project. Samantha graduated from UNC-Chapel Hill School of Information and Library Science in 2014 and is still learning a lot about libraries, including PDA.


What Is an e-Forum?

An ALCTS e-forum provides an opportunity for librarians to discuss matters of interest, led by a moderator, through the e-forum discussion list. The e-forum discussion list works like an email listserv: register your email address with the list, and then you will receive messages and communicate with other participants through an email discussion. Most e-forums last two to three days. Registration is necessary to participate, but it’s free.
