See these locations on Google Maps (prepared by Candace Hill). Clicking on each pin on this map opens a postcard or image of the building as close to 1912 as possible.

Identity of original compiler unknown; document provided to C. Hill by the U.S. National Bahá'í Archives. Presumably written in 1976, as this date is mentioned in the footnote.

The meaning of the footnote references (e.g. "5, 64") is unknown; they could possibly refer to an unfinished manuscript on the history of the Chicago Baha'is, or to an index or numbered notes.
