If you wish to conduct research or otherwise visit our collections we request that you schedule your visit in advance. Our Curator requires time and scheduling to pull objects and set up research opportunities. We generally request a full week in advance of your visit to ensure we have the available staff time and space for your visit. Thank you for your cooperation.

You can reach our Curator by using our Contact Us page and selecting "Research Request," or calling us at 307-872-6435.

One of our specialized community services is assistance with family and local historical research. Our comprehensive library includes books, photographs, oral histories, census records, local directories and more. In order that we may better serve you, please contact us before your visit to allow us time to find materials relevant to your research.

We also offer free vintage firearm research. Our staff will research your firearm and provide a writeup of any information we find. See our history/news section for some of our latest research. Please contact the museum at 307-872-6435  if you would like to take advantage of this research service.

The museum has a research library available to patrons at any time during our regular business hours. It contains some photographs, books (including many out-of-print titles), family and subject research files, an obituary index, transcriptions of oral histories, historic building surveys, local newspapers on microfilm, census records, and other resources. All items must be used on-site; the museum does not check out any materials in the research library. 

The museum also houses extensive archives of historic photographs, records, documents, and publications. As the primary repository for materials recounting the past of Sweetwater County, the museum serves as a valuable resource for authors, researchers, and other scholars of history.

Photographs and documents in archives are available to researchers by appointment only. These materials require special procedures and must be supervised by the curator or director. Please contact the curator if you have questions or would like to make an appointment.

There are fees associated with digital or printed reproductions of photos and documents in the museum's collections. Please see our Reproduction Fee Schedule for pricing.
