Some general information:

What is "the Old Car Manual Project"?

The idea is to scan manuals for old, vintage or antique American vehicles and their components and make them available on the web, for free.

Why are we doing this?

Why not? But really - one of the hardest parts of restoring or servicing old machines is getting decent technical information. Often, it's difficult, impossible or expensive to obtain. We think that this kind of information should be freely available, as a public resource for the preservation of our industrial history.
