Homer Hoyt’s 1933 book “100 Years of Land value in Chicago” is now posted at the Internet Archive. Only a few land value nerds will read it all the way thru, but all should be impressed by the quantity of work Hoyt put into it, describing and analyzing Chicago’s land market for its first century.
This was all done before cheap photocopiers, faxes, and of course computers. I wish someone would update it.
