One hundred leading scholarly publishers now participate in the program, contributing 38,000 titles—including 2,250 published in 2015.

Unlimited, DRM-free access: This year, we began offering ebooks exclusively in a DRM-free access model that offers unlimited simultaneous use, chapter downloads, and printing. This model works just like the journals on JSTOR, and has received an enthusiastic response from librarians and users.

Spanish-language ebooks: We’ve partnered with academic publishers in Latin America and Spain to make important scholarship in Spanish available on the JSTOR platform. More than 700 Spanish titles are now available.

DDA predictor model: A common challenge with Demand-Driven Acquisition is not knowing how long it will take to use deposit funds. To address this, JSTOR developed a model to predict usage and spending for each library based on the experiences of other participants that have a similar level of archive journal usage and DDA profile size.

Faster ebook availability: We’re making titles available faster than ever before. In fact, 98% of our ebooks become available on JSTOR within five days after we receive them from the publisher. We also send an updated catalog to YBP every day to ensure that the latest titles are available on GOBI.
