As a poor college student with little money and a hobby for genealogy I have had to find as many free records as possible over the years. So for this Thrifty Thursday, some of the most important records genealogists have at their disposal: Census Records! Most of these links are for North Carolina censuses, but pages are available for all states on these sites.
A compilation of sites, by state and county, that offer free transcriptions & indexes of census records. Some counties have "Other" types of records as well, like tax lists.
Set up almost like a spreedsheet, the USGenWeb Census Project shows the online transcription status of every census record and the provider of the transcription.
Similar to CensusFinder, Census Online connects users to other sites which have transcriptions & indexes of census records sorted by year and county.
