What's in an Archive?

Watch this 'Archives 101' featuring our archivist Donna Eschenbrenner explaining our process for creating archival collections, and how those collections are then stored and used by researchers.

It is easy to think of history as static, archival collections as immobile snapshots of time. 2020 has been filled with life-changing, and generation changing events. As the keepers of Tompkins County history we found called to actively request reflections and feedback from our community during these historic times to preserve for future historians and educators.

In March 2020 we began accepting submissions for the COVID-19 Archival Collection; gathering images, written reflections, and items from Tompkins County residents of all ages reflecting on their lives during this global pandemic. 

In June of 2020 following a week of nationwide and local protests garnering global support we began a new Black Lives Matter Archival Collection as an addition to our existing Black History collection. Detailing issues, efforts, and actions in Tompkins County related to the global protests against police brutality on black and brown bodies. We recognize the current Black Lives Matter and other solidarity protests emerge out of a long history of organizing, and community action in Tompkins County in response to racial prejudice and police actions.

These collections are ongoing. All submissions for either collection can be sent to or for physical items please contact us to arrange a drop-off time.

We are always striving to make our collections more accessible, and these days that means we get a lot of questions about digital copies and online databases. We are moving towards digitization for some collections, such as our HistoryForge database of Ithaca census records from the 19th and 20th centuries; but digitizing any collection takes a lot of time and associated cost to ensure the collection is easily searchable. The Smithsonian Archives released an excellent interview with two of their expert archivists detailing some of the difficulties with digitization that you can read here

We have partnered with other local organizations, including the Tompkins County Public Library and the South Central Regional Library Council's New York Heritage to host some of our materials on their platforms:

We are eager to explore more opportunities to further this important initiative to make our collections as accessible online as possible.
