Attempting to Obtain a Costume Resource Book Legally

Still working on the hand sewing which has been successful despite some snags. I just have one possible stupid question. Does anybody know one could obtain (legally speaking) a copy of Textiles for Regency Clothing 1800-1850: A Workbook of Swatches and Information for a somewhat reasonable price. Is it even in-print? ( I am not sure if it is.) I tried Amazon.com but no such luck. I appreciate any suggestions. Thanks!
