TITLE: Borel's Paris Lectures
QUESTION [9 upvotes]: I am trying to read Harish-Chandra's book on automorphic forms on Semisimple Lie groups, and he keeps referring to Borel's Paris lecture notes. Does anyone have an online version of these notes or know how I could get it? Ensembles fondamentaux pour les groupes arithmétiques et formes automorphes, Lectures at Institut H. Poincaré, Paris 1966 (Unpublished, notes by H. Jacquet, J.J. Sansuc and B. Schiffmann)
Thanks!

REPLY [13 votes]: The Paris lectures, along with others he gave later, were spliced together into a publication:  Introduction aux groupes arithmetiques (softcover, Hermann, Paris, 1969).   As his nominal assistant at IAS in 1968-69, I tried to help with the splicing process but didn't manage to clean up all the inconsistent notation and typos (especially on pages 90-94) which I later jotted down for myself.   There was some time pressure, not to mention his many other projects at the time, so the finished product is useful but imperfect.   By now it's also probably hard to locate outside some libraries.
