OSA's Extended Backfile Policy

(updated for 1 January 2019)

As in 2018, institutions subscribing to any of OSA's package products will continue to receive complimentary access to the complete backfile for all titles included in the package subscribed to in 2019.

For those institutions that subscribe to an individual title or titles in 2019, OSA will extend complimentary access to the prior 12 years or back to 2007 (instead of the 11 years covered in a 2018 subscription)—in addition to newly published content in 2019—to ensure that libraries do not have an interruption of access to the 2007 content.

There are four other options available for those institutions looking for complete access to the backfile for a specific title or titles:

  1. Adding the Extended Backfile Product to the Purchase of a Subscription. Subscribers who wish to provide access to all available content related to an individual title—rather than just back to 2007—will need to subscribe to the "leased extended backfile" product.
  2. Upgrading to One of OSA's Package Products. OSA provides complimentary access to the complete backfiles of all products included in its various package products including E-Combinations 1 through 4, Optics InfoBase, and Optics InfoBase Premium.
  3. Purchasing One of the Single Title Digital Archive Products. OSA offers several Single Title Digital Archive products. Institutions can purchase perpetual access to the archives of Applied Optics, Optics Letters, the Journal of the Optical Society of America A, and/or the Journal of the Optical Society of America B. Each single title Digital Archive includes access to all content published for that journal—from issue 1 to 2006. Since all 2019 journal subscriptions provide access back to 2007, a purchase of one of these single-title Digital Archives will enable an institution to provide complete access to all content for the single title(s) purchased.
  4. Purchasing One of OSA's Digital Archive Package Options. Institutions interested in providing access to the full backfile or portions of it in perpetuity can make a one-time purchase for one of OSA's Digital Archive package products. They include the OSA Centennial Archive (which includes more than 256,000 journal articles and conference proceedings from 1917 to 2015); the OSA Digital Archive 1 (which includes roughly 135,000 journal articles and conference proceedings published between 1917 and 2005); and the OSA Digital Archive 2 (which includes more than 121,000 journal and conference proceeding articles published between 2006 and 2015).
