There are several sources of US Census data on CD-ROMs. A good place to begin looking is any one of many genealogy sites on the web. Most of these sites have links or stores where you can purchase various genealogical references, including the census. Some of the sites also allow you to read these records on the web site if you are a member. Independent of the genealogy sites are private companies who will custom prepare a census CD for you -- these firms can be located on-line via an internet search. Of the census data I've seen, 1880, 1890, 1900, and 1910 are available for most states and many of the counties within the states. Costs are variable.
