Documents representing the finances of the municipal government's routine transactions. Bills are present in large quantities, often with several hundred grouped under a single HRS number. The city incurred charges for a wide variety of items and services including printing, paving, killing dogs, fire plugs, wharves, equipment and supplies, quarantines, and labor to improve the Baltimore harbor. Vouchers are also documents submitted for payment, but these items were individually numbered, where the bills were not. In general, the vouchers cover charges that were allocated to specific appropriations.

Cancelled checks represent payments for the various bills and vouchers and other obligations incurred by the city.

The payrolls, which form the final component of this series, do not cover all city employees and are not present for each year.

Examples of people employed by the City represented here include jurors, street cleaners, Lamplighters, and janitors at city hall, but there are vast unexplored areas of city expenditures here that bear on documenting the contributions of the City population to public works projects, landscaping the city through public parks, the development of public transportation that remain inaccessible to researchers without item level analysis and access that has yet to be provided.
