Businesses named in the atlases

43 businesses

Every Sanborn volume opens with a printed index naming the town's mills, tanneries, hotels and works by proprietor. Those indexes were read off the scanned sheets by machine and then matched to each other, so a business surveyed four times appears here once, with the years it survived. 10 of these 43 were named in more than one atlas. Each carries a crop of the line it was read from: the spelling is the recogniser's and the 1880s lithographer's, and the scan behind it is the proof.

The townships, in 1915

516,512 words

History of Union County, Ohio; Its People, Industries and Institutions devotes a chapter to each township: its boundaries and streams, who settled it and when, the mills, the schools and the churches. All 3 are reproduced here in full. Each row shows the township's own shape and where it lies in the county, drawn from the Census Bureau's boundary. Which settlements belong to which township is computed from that same boundary, not taken from the book.
