My local library has one book on chainsaw repair and a couple on homeowner how-to-use.
I find the one they have for repair is excellent. It is by Intertec and is the 10th edition. They have several older editions that cover many vintage saws. I don't know if it is the best place to start. But, short of an original service manual for a saw and/or being used as a supplement to other sources, it seems to help. It has helped me sort out some of my questions.
Edit: I forgot to add they cover many different manufacturers and series in each edition.
That looks exactly like the Clymer book.
