Okay, so a link on Census record transcribing may not be the coolest I’ve put on this site, but it may be one of the most important. The US Census records go back all the way to the 1700s, and a lot of these records have either not been digitized at all, or only rough copies exist in many different formats. Due to age, use, insect and water damage, etc., some of these records are in danger of disappearing forever. Many others are difficult to use because of the varying formats. Because of this, transcribing them into a standardized digital form is critical.
This site allows anyone from the general public to choose individual records and volunteer to transcribe them digitally. No experience necessary! The site gives basic walkthroughs and other how-to information, so anyone can do it, and at their own speed in their free time. Just click on the state and area of your choice and go from there.
