Abstract: 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.

Acquisition Information
35mm Slides included in the Yosemite Slide Collection were originally housed in the attic of the Yosemite Valley Museum Office.
An inventory of the Audiovisual Library from 1970 created by Helen L. McClendon indicates a total count of 45,757. By 1998
the Library was stored in metal filing cabinets in the Archives Annex office space in El Portal and managed by Norma Craig.
At this time Norma estimated the collection consisted of 100,000 slides. As early as 1988 Norma Craig began assigning local
accession numbers to slide acquisitions. These local accession numbers pertained only to the Slide Archive. Norma's local
accession records note the name of the donor, extent, subject matter, and, at times, the copyright status of the images. Local
accession records are stored in the Yosemite Slide Collection folder in the Archive Annex office. Accessions were also tracked
in tabular form by Norma.
Norma Craig retired in 2005. In May of that year the Slide Library was accessioned as one field collection, YOSE-06815. Many
slides were previously accessioned into the museum collection, and were accounted for upon processing and cataloging.
Biography/Administrative History
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.
Scope and Content of Collection
The Yosemite Slide Collection is organized based upon the hierarchy established by Norma Craig, Slide Librarian until 2005.
During Norma's tenure the slide collection was continuously being accreted to. Given the collection's constant state of change
Norma established a hierarchy based not only on the slides currently in the collection, but also on topical subjects anticipated
to appear in the collection.
Presently, the Yosemite Slide Collection is organized into eleven series. The first eight series are based on the physical
environment, natural resources, cultural resources, visitor activities, and park management and history as follows: A-Scenic
Images; B-Pictorials; C-Physiography; D-Plants; E-Animals; F-Ethnography; G-Visitation; H-Park History and Management.
The final two sections are reserved for collections gifted to Yosemite National Park. In these cases it was important to retain
the original order and provenance. Images were kept in the order they were received from the donor whenever possible. These
include: J-Donated Collection; K-Concessioners Collections.
Each series is further broken down into subseries and sub-subseries. Beyond the sub-subseries level items are arranged by
item number. During processing and cataloging unique slides are assigned a ten-digit item number based on series letter, subseries
number, and sub-subseries number.
