I recently picked up an old Sears and Roebuck 3speed and am interested in fixing it up- what books would be helpful for me to have?

I have a Raleigh that I love and ride a lot, but I don't have a lot of experience working on it. So far, I have only done maintenance work.

Right now I am taking this old bike apart and cleaning it, but I am sure something will fall apart, break, or get lost in the process.

Anyway, what are your favorite bike maintenance manuals/handbooks?
