The information is listed for each resident entry and there is also a section to look up an address and obtain the new number. Often, the numbers were quite a bit different. FYI, odd numbers are either the northside or eastside of a street; even numbers are on the southside or the westside. Baltimore City Directories have been microfilmed and distributed.
