I came across this reference thought might interest some of you. It was recommended by Dorothy Barenscott on her blog Avant-Guardian Musings. It's called ART HISTORY: A PRELIMINARY HANDBOOK, by Dr. Robert J. Belton. It is online and free to use.
It looks like an excellent resource for persons like myself who are studying art history and in the process of defining my own art practice.
Thank you Dorothy for sharing this resource.
