Hi all, someone started a page on the nLab that listed the locations (and, where possible, websites etc) for the annual(-ish) CT conference. There are some gaps even as recently as the last 20 years, and the current oldest item is the 1989 Bangor CT. https://ncatlab.org/nlab/show/Category+Theory+conference In looking around, I suspect that in some years (before my time) the conference may have gone under a different name, or was combined in some way. For instance, was it ever held at MSRI? And, of course, it may not have been held in some years (2012?) If people can supply some info for 1993,1994,1996,1997,1998,2001,2002,2003,2005,2012, then at least we will have the last 30 years recorded. I think I know where to find some info about the 1980s (Bob Paré's list of conference talks! https://www.mscs.dal.ca/~pare/Conferences.html), but getting a full list would be good, inasmuch as that is possible. Perhaps there was a published list in a proceedings of the history at some point? Thanks.
