               Anders BJ\"ORNER,   ``Shellability -- a Nonpurist View''


The papers [5,6, 7] on which the talk is based are still being written
(January 1994) but will hopefully be available at the time of the
meeting. The other items are places where one can read about pure
shellability in the sense in which it will be discussed here.
