The dataset is a compilation of prices of public securities (equities and bonds) traded in nine United States securities markets and in London during the period between the United States Revolutionary and Civil Wars. The data were gathered by scanning early United States periodicals chronicling the period from 1786-1862. The data were concentrated on what were termed “runs” of securities quotations broken down by days, weeks, or months for each of the ten cities in the data set. Runs are series of bids and offer quotes for different securities and maturities. Within each part (market), the data were divided by issuer sectors or types. There may be some redundancy in the data, because when there was doubt about categorizing similar issues under a key code they were categorized under separate codes.
