The Thursday afternoon and Friday morning seminars

In the fall of 1983 Langlands and others held a seminar at the Institute for Advanced Study (Princeton) on Thursday afternoons, and Langlands and Jean-Pierre Labesse ran a seminar Friday mornings on the twisted trace formula. The notes from the lectures are in the process of being put to TEX, but in the meantime I post scans of the originals (done by Alice Garber at the Institute in Princeton). Not all lectures were written up for distribution.
