The Yosemite Research Library contains thousands of materials, including rare books, articles and photographs, all focused on the park’s fascinating history. Since the 1920s, people have pored through the documents and images, perusing original bound copies of Yosemite Nature Notes, studying old maps or reading about early ascents of Half Dome.

Through this 2016 grant, a team of park staff, interns and volunteers made major strides in modernizing the library’s collection, which has grown exponentially over the years. They took on the enormous task of converting the collections to the Library of Congress classification system. That important shift makes documents easier to locate and aligns the Yosemite catalog with standards used by research organizations around the world. They also added thousands of items to the National Park Service’s online library catalog, and launched a new Yosemite Research Library webpage that offers an engaging overview of the library’s history, services and materials.

Your gifts funded key steps to modernize a long-standing Yosemite institution so that the park’s rich history can be preserved and celebrated for years to come. Park staff estimate that the upgrades and new resources made possible through this funding have increased access to the library’s collections by 80 percent. Thank you for supporting your park!

Project Notes

The Yosemite Research Library is an extremely specialized research resource and it has grown exponentially in the last 90 years. Converting to the Library of Congress system would allow researchers to more easily find the resources they need, and allow for greater specialization in identifying resources.
