Patron-Driven Acquisitions/Demand-Driven Acquisitions: The Good, the Bad, and the Ugly

The live discussion took place August 5 and 6, 2015. Read the discussion messages.

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.  This e-forum is intended to be a platform for current PDA/DDA users to share their experiences and for nonusers to ask questions. These prompts started discussion:

  • Which should we use?  Profiles or ollections?
  • 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?

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 discussion list: 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. See a list of upcoming e-forums.

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