Demand-Driven Acquisition | Alexander Street

Demand-Driven Acquisition

How can you provide patrons with broad access to video on a limited budget? How do you ensure resources are relevant to patrons? With a DDA membership, of course.

  • With Alexander Street's DDA your users get access to 53,000+ video titles.*
  • DDA gives your patrons the power to determine what streaming video content you acquire.
  • After a set number of video playbacks, the usage automatically triggers a subscription to specific single titles. Most DDA titles have the option to upgrade subscriptions to perpetual ownership. 
  • Your patrons choose the content, you choose the terms. It's as easy as that!


  • Custom profiling made easy: Alexander Street allows you to customize and manage your DDA account. By publisher or subject, YOU decide what films to expose to your patrons.
  • Access-to-Own:  Automatic perpetual ownership of qualifying titles is granted once you've reached $499 in invoices for a title.
  • Admin Portal Value-Adds:  Custom MARC records, easy access, and a focus on engagement and impact data.
  • No Start-up Fee: Access is turned on and no charges are incurred until the 4th time a title is viewed beyond 30 seconds.
* All titles not available in all regions



  • Access-to-Own:  Tired of paying year after year to renew popular films?  Access-to-Own perpetual rights is now granted for qualifying titles once you've reached $499 in total invoices per title.
  • No Start-up Fee: Access is turned on and no charges are incurred until the 4th time a title is viewed beyond 30 seconds. Then an invoice is triggered for a 1-year subscription to that film. You may choose to upgrade to a 3-year subscription, or perpetual rights (available for most titles). Your patrons choose the content - you choose the terms.

How does Alexander Street’s DDA program work?

Your patrons will receive access to videos without any setup fee or upfront commitment. Users will be able to search and stream with complete interface functionality, as if these titles were already a permanent part of your holdings.

To help you manage your budget, we offer a spending cap feature that ensures you stay within your budget even if your patrons are highly active users. You can increase your cap during the DDA period. Additionally, title-level suppression prevents your users from seeing or using content you don’t want to acquire.

The DDA program also provides a detailed admin portal that helps you monitor your account’s activity. You can see which titles have been recently triggered with 24-hour currency, track your spending against your cap, and upgrade triggered titles to multi-year subscriptions or perpetual purchases when rights are available.

What support will I receive?

DDA at Alexander Street comes with consultative support including usage tools, training resources, COUNTER-compliant usage stats, title suppression capabilities, budget management tools, and more.

PDA allowed us to increase access in a cost-effective manner. But it has to be easy to implement and manage.
