Collection Overview
Table of contents What's This?
The Yosemite Slide Collection contains 2"x2" 35mm color transparency slides. The slides include original cardboard or plastic mounts. Metadata is often written in ink or pencil directly on the slide mount or printed on an adhesive label and placed directly on the mount. 3"x3" color transparency slides are located throughout the collection, and have been called out in the summary field. The Yosemite Slide Collection also contains 4"x2" stereo slide mounts. Two View Masters are stored with the Yosemite Slide Collection for viewing stereo slides in 3-D. Within the sub-subseries Interpretive Slide Shows (H-03-09-yyyy) there are associated audio cassettes, 8-track audio tapes, reel-to-reel audio tapes, and floppy discs containing media designed to complement prepared slide shows. Within this sub-subseries there are also paper transcripts outlining the Interpreters verbal content presented during prepared slide shows. The majority of images were taken between 1950 and 1998. Images from the Historic Photograph Collection, which is managed by the Yosemite Research Library, were reformatted into 35mm slides and are included in the Yosemite Slide Collection. These images date back to 1867. Historic photograph reproductions have been incorporated into the established Yosemite Slide Collection hierarchy based on subject matter. When possible they have been called out as a sub-subseries titled Historic Photographs and located at the end of a tropical series and subseries. All images within the collection pertain to Yosemite National Park. Yosemite's landscape, natural resources, cultural resources, influential personalities, architecture, management history, and park partners are all represented in the collection.
The Yosemite Slide Collection was managed by the Museum Branch in the Interpretive Division as part of the Audiovisual Library, also known as the Visual Center or Yosemite Museum Slide Archive. It is an artificial collection of slide acquisitions donated to the museum branch, as well as images taken by National Park Service employees to document the conditions, management, activities, and resources of Yosemite National Park. Historically, the Visual Center functioned primarily as a resource for Interpretation Division staff when creating interpretive programs for the general public. However, the Yosemite Slide Collection was, and continues to be, open to requests by any entity including park partners and the public.
