For starters I have:
Lecture Before the Madison County Medical Society, By Dr. Alvin Foord,
Cazenovia, NY, July 1867
A fascinating lecture discussion the class differences in Cazenovia and the nation at the time. Emphasis on Dr. Foord's concern that desirable people (old family WASPs) were controlling their birth rate through prevention and abortion, and how imigrants (the Irish) were having many many children.
of the Road District Descriptions, 1804 to 1832, from the Cazenovia
Town Road Book
A great way to find where people lived over the first few decades of our history (Nelson, Smithfield, Fenner, and part of DeRuyter were within Cazenovia until 1807 and thus early roads in those towns are included)

This is a report on the trends in agriculture compiled from census data by Cornell University Dept. of Ag Economics. There is little text, a bunch of tables, and several graphs. Sources are listed at the end.
