Access that reflects real reader engagement
With EBA, libraries get:
- Unlimited access to a growing corpus of 87,000 high-quality, backlist scholarly ebooks from 115+ of the world’s leading scholarly publishers—all for a predictable, flat annual fee
- One year of unlimited DRM-free access to titles, followed by the opportunity to select titles for acquisition based on usage data
- Unlimited access to millions of dollars worth of ebooks per year at a fraction of the cost
- No additional participation or platform fees


How EBA works:
- Libraries pay a one-time fee to access all ebooks in the program, 75% of which is used to acquire ebook selections at the end of the access period
- The upfront investment provides one-year of unlimited access to our growing EBA ebook collection
- Access periods run for 12 months on a January – December or July – June cycle
- Towards the end of each year, libraries use real usage data to decide which titles to acquire for perpetual access on JSTOR
What makes the combination of EBA and DDA work for us is being able to get the MARC records in and out automatically. To the reader, there’s no difference in how the ebooks are discovered or accessed.
