Thanks to the efforts of the Poindexter Library, 18 of the past years' lectures have been recorded as mp3 files and soon there will be more. I will periodically upload lectures linked to this website, however, it is my hope this summer to develop a website specifically designed for the annual lecture and to have all the digitalized lectures available there. Last year's lecture by Peter Kreeft is available for listening here under "Recorded Lectures".
The 1996 lecture by Marjorie Mead can now be heard under the same link above for the Kreeft lecture. The 1998 lecture by Douglas Gresham may also be heard via the same link.
