In October footnote.com announced that it was digitizing and creating a searchable database for all publicly available U.S. Federal Censuses, ranging from the first U.S. census taken in 1790 to the most current public census from 1930. Through its partnership with the National Archives, footnote.com was adding 9.5 million images featuring over half a billion names to its extensive record collection. With over 60 million historical records already online, footnote.com will use the U.S. Census records to tie content together, creating a pathway to discover additional records that previously have been difficult to find.
Footnote also helps you find and share historic documents. They are able to bring many never-before-seen historic documents through their partnerships with not only the National Archives but the Library of Congress and other institutions. All of their indexes are open and free to search. You can find names, places and topics. Each search returns a list of documents and small image of the document. Viewing the full image of everything is not free, but they have opened up a select number of titles that are including:
