Due to budget cuts, the Oregon Historical Society Research Library will be closing on February 28, 2009. After that date, collections will no longer be available to the public. At this point, photo and film reproduction orders will still be taken.

The Trustees concentrated most of the staffing reductions in the research library in order to preserve and focus on public access to museum exhibits and educational programs and to continue web-based services, traveling exhibits, and school outreach programs across the state. “The reduction in expenses will allow us to focus on excellent core programs that serve more than 50,000 Oregonians each year.” Said George Vogt, Executive Director.
The budget hit was a triple whammy - reduced state funding, reduced endowment funding, and reduced annual giving.
