The creation and design of web access to the Yosemite Research Library is made possible through the generosity of Yosemite Conservancy donors who supported the 2016 Yosemite Research Library project. In 2016, park staff and interns began to modernize access to the resources protected by the library, which have grown exponentially over the years since its opening. The work on the website and digital catalog of library holdings are part of this project.

The Yosemite Conservancy is dedicated to enhancing the visitor experience and providing a deeper connection to the park through outdoor programs, volunteering and wilderness services. Learn more at yosemiteconservancy.org or call 415/434-1782.
