Finding materials in our collections
The holdings of the Tretter Collection are described in a variety of databases and discovery tools. At the moment, the two main tools for discovering our collections are:
- the Tretter Collection's finding aid portal, and
- a targeted search for Tretter Collection materials within the University Libraries' central catalog
To read instructions for using our finding aids, click here. To learn more about finding, accessing, and using online materials from the Archives and Special Collections, click here. Please contact us if you need additional assistance finding or selecting materials to request.
Our collections are non-circulating. Materials are housed in secure, non-browsing stacks and are retrieved for users upon request. Some of our collections are stored in an off-site facility, requiring extra time to retrieve materials for patron use in our reading room.
Regrettably, due to limited staffing, we cannot accomodate walk-in researchers. We request that you contact the Tretter staff at least a week in advance of any planned visits to the Archives (if possible) to make an appointment and to request materials. Send an email to firstname.lastname@example.org or email@example.com with your request, and please include in your message:
- the date & time you wish to come, and
- a list of the specific boxes from the collection you wish to see. (Consult our finding aids and catalog records––accessible via the links above––to locate specific materials of interest.)
Feel free to contact us if you need assistance locating or selecting materials to request.
