Sally [et al.], We've made use of the GeoLytics disks for years--they were the first product that made it easy to download census data and GIS files. But the particular product you mention doesn't have block-level files. (You can now get 1980 block-level data but _not_ GIS boundary files from NHGIS).

Hi, Does anyone know whether 1980 U.S. Census block maps are available online somewhere? Plain and simple images would be fine. (I hope someone will correct me if I'm wrong, but it seems that vector data are just not available.) Many thanks. Chris Winters University of Chicago Library
