The Crush collection is divided among the following series: County Records, Altizer Family Papers, Sullivan Family Papers, Politics, Military, Local History, and General Materials.

The County Records series contains tax records dating back to the late eighteenth century, a few scattered court records from the early nineteenth century, and records of the Montgomery County overseer of the poor from the late nineteenth century. The Altizer Family Papers consist of a three items of personal correspondence, while the Sullivan Family Papers contain receipts and tax records from the latter nineteenth century. The collection also contains a small file of materials relating to state and local politics during the 1920s and 1930s. Crush's involvement in recording and preserving local history is revealed in both the Military and Local History series, the former containing rosters and notes on local units, the latter including typescripts and printed materials on a variety of subjects relating to early Montgomery County history. A small set of general materials includes personal papers, ephemera and a photograph of Montgomery Male Academy.
