Q. Is there a resource that indexes past employees of national parks?
I am working on a photograph project that lists names of individuals pictured, but does not list what their position was. I am mainly concerned with Utah Parks (Zion, Bryce, Grand Canyon, etc.), Death Valley, and Yellowstone during the late 1800s up until 1950s-60s. Thank you!!
There is a listing of public parks officials. http://unomaha.worldcat.org/oclc/24017838 If any of the persons in the photos are park directors they will be listed in this book.
Otherwise, there are a few options you can try. First you can try searching for individual names in HathiTrust http://www.hathitrust.org/. HathiTrust has many government documents in full text, especially the older documents and you might find information about job titles there.
