He is active in other regional heraldic organizations. He has lectured widely on a variety of heraldic subjects, in particular on his own research on the heraldry of Europe and on local heraldry.

"""This volume is the most international study of heraldry for a generation. Well known for his irreverent lectures, which bring obscure historical subjects to vibrant life, Stephen Slater's book is sure to appeal as much to the general reader as the enthusiast.""
