This collection contains audio recordings for 186 different lectures, which have been digitized and are available online to Columbia affilates (and available to our public in our reading room). While the majority of the recordings are from the GSAPP Wednesday Night Lecture series, there are some recordings from other GSAPP sponosored symposiums, panels, and talks. The recordings are arranged in chronological order, with undated recording listed last. No paper records for this lecture series are included in this collection.
