As the site says, “Our specialties include Theology, Philosophy, Medieval and Patristic Studies, Greco-Roman and Judaica Studies and all related subject areas. In addition to these categories, we also have a general selection to choose from. We have 16 years of experience in buying and selling scholarly books in North America and abroad.”

There are two pages of interest:

St. Thomas’ Works: http://www.henrysbooks.com/?page=shop/browse&category_id=37&CLSN_3313=126020346133133dd3eb3f37934e0735

Also, Lulu’s results are not that bad either: http://www.lulu.com/browse/search.php?fKeywords=Thomism
