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.
