After getting permission from Jean B'enabou's son for doing so I have made copies of some of his most influential unpublished texts on fibered categories available on my home page under https://www2.mathematik.tu-darmstadt.de/~streicher/FibCatTexts/ jb_montreal_74.pdf are his notes for the 1974 course in Montreal jb_lln_80.pdf are J.-R. Roisin's notes of Benabou's famous 1980 course at Louvain-la-Neuve jb_chapitre1.pdf is a copy of Chapter 1 of his never finished book "Des Cat'egories Fibr'ees" In 2 folders at the same place you find copies of the Theses of Celeyrette and Moens. The first one was directed by Jean himself and the second heavily influenced by Jean's 1980 course. The copies are partly of moderate quality but readable with a bit of good will. Would be great to have them typed within TAC Reprints series! Jean's work was very influential but not easily available. Hope these copies make it easier for younger people to form their own opinion about seminal work overshadowed by controversies in the past... I am grateful to Jonathan Weinberger for helping me to prepare the copies. Thomas Streicher [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
