I came across this site and this event a bit back. The "Thomistic Seminar" is an annual meeting at Princeton, more akin to a graduate seminar—taking place in a single week's time—than a conference with papers' being presented and discussed. The seminar sports a full and attractive web site, with information about its present doings, as well as past seminars. Also listed are the faculty for this summer's seminar, including David Gallagher and Gyula Klima.
