DDA "Data Driven Acquisition" - Also referred to as PDA (Patron Driven Acquisitions). Titles are generally triggered for purchase in a dda plan by use. The number of uses for each plan is different.
We currently have a DDA program through JSTOR for ebooks (7 triggers). We only have the latest three years (frontfile) through DDA Publishers remove ebooks from the JSTOR DDA program often. The title pool is refreshed once a month for discovery on OneSearch. The true title list can only be seen in the JSTOR admin account, but if you sort the list at the JSTOR website by frontlist that may be close.

While not ebook related, we also have a smart dda through Kanopy for streaming video. The Kanopy PDA title pool is curated based on past use. Acquisitions also receives mediated requests through Kanopy from patrons suggesting titles.
EBA "Evidence-Based Acquisitions" - Under an EBA model, we can choose to access a large pool of title and then choose titles with perpetual access at the end of the EBA cycle. Our selection cycle for the EBA model usually occurs in May or June. The evidence to support decision-making is supplied in the form of usage reports, indicating which titles are the most popular within our institution. We have several Ebook EBAs currently. See the files in the Collection Development Assembly (CDA) Team for more details about current EBAs.
DRM-free - DRM is a set of techniques that restricts the access, copying, and sharing of copyrighted digital media files. For instance, DRM typically limits how much an e-book reader can print and how long they can check it out. DRM-free content allows users to freely use and transfer the content without any limitations. Buying directly with the ebook publisher usually provides a DRM-free experience. Often the price when buying direct is the same as buying the same ebook through an ebook distributer. Contact acquisitions to learn more about special pricing or discounts available. Often when we purchase ebooks direct they are DRM-free - Cambridge, Springer-Nature, Taylor & Frances, or Wiley are some examples.
Ebook subscriptions with drops. Several selectors have asked about the titles that fall out of the ebook subscriptions. Proquest Academic complete is one of those subscriptions. Proquest sends a list of titles that will be dropped twice a year, usually. Most often in December and in June. Ebsco also has several ebook subscriptions where titles are dropped often. We do not usually receive notice of these drops.
OverDrive contains some ebooks with expiring licenses similar to the streaming video licensing model.
