Another useful repair book is "Bicycling Magazine's Complete Guide to Bicycle Maintenance and Repair" published by Rodale Press. Most are long out of print but Amazon seems to have several of the revisions and updates. Mine is the 1994 edition and spans the transition years from freewheels and friction shifting to freehubs and indexing and should be a good version for you. Amazon also has the 1986 edition which will cover "vintage" bikes in more detail.
