Everything (Literally):
- Archive.org - This site has Multi millions (if not billions by now) historical documents, music, movies (downloadable), Civil war records, books. You name it. Just an enormous undertaking to preserve data from historical archives all over the world.
Output: When searching for information, you may try their search engine, but I find it quite lacking. Instead use google and qualify the site to archive.org
Example - Suppose you're into genealogy, and looking for a book written in the 1800's named 'Vital records of Beverly, Massachusetts, to the end of the year 1849'
search on google: [i]'[/i]Vital statistics Beverly Massachusetts site:archive.org' Note the site qualifier. All results will be for archive.org. Click on the
link: 'Vital records of Beverly, Massachusetts, to the end of the year 1849 ...'
Note the following on archive.org:
