Can I highly recommend the latest book from that walking wikipedia of Scottish heraldry, my dear friend Eilean Malden FHSS. Arma Scotica:
This illustrated survey, is the result of twenty years work by Eilean Malden and looks at some 140 armorials from 1380 to 1707 and gives a data sheet for each which contains details of title; location; date; binding; watermarks; size and provenance and the total number of coats of arms contained.
