Following that link, a search leads to http://mathdoc.emath.fr/archives-bourbaki/PDF/nbt_029.pdf where we find Le Tribu no. 28 (reporting in a meeting of June-July 1952). Page 3 includes this report on the state of Theorie des Ensembles Ch. 4, Structures:
Le Congrès à travaillé pour dégager la notion de homomorphisme.
The context is interesting. The point is, this confirms what was already known, that Bourbaki worked to find a general notion of homomorphism after Weil (1951) suggested they should. And Weil had named Mac~Lane as suggesting the idea. best, Colin .
=================================================================== Pierre Cartier, Chritian Houzel, Andrej Rodin and Ralf Krömer wrote about that issue.
You will find the source material, i.e. the early Bourbaki archives (1934-1954), which show various early attempts at defining "structure", online at http://mathdoc.emath.fr/archives-bourbaki/ A bibliography of sources on Bourbaki is at http://poincare.univ-nancy2.fr/Actu/?contentId=9473
One may not confuse any edition of the first volume of the Elements with Bourbaki relatively evolving thoughts on this matter.
There is a lot to be learnt from reading the sources. Please notice that I replied to you personally and not to the whole list. Be kind to a shy person. Best regards, LB ====================================================================
