One of the main goals for genealogists is finding marriage information about their ancestors.
Over the past few decades, thanks to volunteers, librarians and archivists, a great number of indexes to marriage collections have been provided for free online. These searchable indexes provide specific marriage license, bond, and certificate information, and sometimes scanned images of the actual marriage documents themselves. These free online collections have hundreds of millions of records in them in total.
