I was trying to find a good example in evidence explained to follow and am not sure I made the best citation. This is for an original record in loose paper files in the Baltimore City Archives. Records are sorted into record groups, sections etc. Documents are in numbered document order which do not necessarily fall by date just more of a random assortment with each numbered and usually grouped in a year or something similar. Any thoughts or better models would be appreciated.
Baltimore City, Maryland, Baltimore Record Group 3, Series 1, Baltimore City Commissioners 1797-1899, box 27 (1821), Petitions and Applications, document 31 "Bond and Gough Streets, request for well and pump"; Baltimore City Archives.
