re:  Megan Weiler-Hill's query about articles on conservation
problems posed by unstable materials in recent works.

Megan, try:

Kimberley-Davenport, - impossible liberties:  contemporary artists on
the life of their work over time - Art Journal, vol 54, no.2 (summer
1995), 40-52 (terrific article)

Jackie Heumann (Ed) -  From marble to chocolate:  the conservation of
modern sculpture - (London:  Archetype Publications, 1995)  (papers
from a seminar at the Tate Gallery, London, 18th - 20th sept 1995)

I would be very interested to hear of other refs - so thanks for
mentioning the Art in America piece.
