Photocopying photographs

On Sept. 19, Barbara Brown at the University of Texas asked for
information on whether photos could be safely xeroxed.  The last real
research on this that I am aware of was done by Gary Saretzky and
published as "The Effects of Electrostatic Copying on Modern
Photographs" in the Book and Paper Group Annual in 1985, v. 4.  It did
not apply to early photographs, but it found that photocopying multiple
times hardly affected his test photographs at all, even those that were
deliberately processed poorly.  Although the light is bright, it has
such a short duration that it does little harm.
