New to large format photography and picked up a lens on the cheap today, but it doesn't list the focal length. I've found some ways to find the focal length, but was wondering if anyone already knows?

I've also seen a reference to a book by Woody Woodsen, but can't seem to find a copy at any of the libraries near me.
Thanks in advance for the help.
