## Research material

** Publications **
I am making as much of my published work
available as I can.
I have put together a collection of
Pre-millenium Papers,
that is, papers covering the year 1976-2000. I am also trying
to maintain a collection of
Post-millenium Papers,
papers from 2001 onwards.

In addition I intend to keep annotated records of publications by
decade. Some of this is more complete beginning of April 2016.

Publications 1971-80

Publications 1981-90

Publications 1991-00

** Miscellaneous Resources **
I aim to have a page with Unpublished Work and other miscellaneous
material.

I have a fairly random selection of slides.
In the case of talks given
in the last few years I am able to give confident dates and venues.
In some older cases the slides have been retrieved from filing cabinets
and I cannot place them with any certainty. I am happy to hear from
anyone who can. Also if anyone can retrieve the slides which
I left in Edinburgh after a series of talks on (I think) Abstract
Games then I would be grateful to have them. They might have more
than historical interest.
