Now, thanks to The Internet Archive, (part of the WayBack Machine) microfilm is coming right to your computer! Here is their description of the focus of this project:
As books become old and begin to fall apart, librarians depend on microform to preserve their content for the future. Tiny photographs on long strips of film (microfilm) or small cards of film (microfiche) are all that remain of hundreds of thousands of documents that have disintegrated over the last century. While microfilm is perfect for storing and protecting this material, it is a does not allow for much access. In following its mission to provide universal access to all human knowledge, the Internet Archive is teaming up with libraries all over the world to begin digitizing microfilm and microfiche. The goal is to get as much content off the shelves and online.
The books in this collection are from a variety of libraries including the University of Chicago Libraries, the University of Illinois at Urbana-Champaign, the University of Alberta, Allen County Public Library, and the National Technical Information Service.
You may also want to view the newspapers that have been digitized from microfiche.
