I have been reading a number of papers by Jacques Tits (mostly written in the second half of 1980s) and in them he frequently refers to following publications of his:


1. Résumé de cours, Annuaire du collège de France, 81e année (1980-1981), 75-86.
2. Résumé de cours, Annuaire du collège de France, 82e année (1981-1982), 91-105.


Unfortunately I have not been able to locate these two papers (internet, library, faculty). Any help with finding these two would be immensely appreciated. 



"Résumé de cours" by Jacques Tits
I've randomly acquired from Tits just a few of his resumes: 1979-80 (Bruhat-Tits work), 1980-81 (Kac-Moody algebras and groups), 1990-91 (Galois cohomology of semisimple groups over global fields). These are all quite short and not likely to add too much to related published papers, but if other means fail I could copy the 1980-81 resume and mail it from UMass if you supply a precise mailing address. (See my home page for contact information.) 


One option is to write directly to the College de France requesting copies. Tits himself has long been retired and is not in good health, but the staff at the College might be helpful. As far as I know the resumes do not circulate through libraries and the like. The College is an ancient institution but has adapted to the Internet age: [links](http://www.college-de-france.fr/default/EN/all/historique/jacques_tits.htm).


ADDED: Digging further into my file, I also found a preliminary draft of the 1981-82 resume. I don't know whether any changes were made in the printed version.
