Emanuel Andrade asked about color photocopies of photographs.
        At my institution we regularly use color photocopies for display
and have found them to be fairly stable, at least for several years under
fluorescent light.  Considering the instability of some color prints, the
copies may well prove to be more stable if displayed.
        If color is not a critical issue, I'd suggest regular photocopies.
Many researchers use the copies to see what the photo is about and then
want to see the original anyway, so maybe having color photocopies isn't
that important.  I know if a person is doing "real" research in
photography, he/she will not be satisfied to see anything except the
original.
        I'd also considering making two copies while I'm at it.  One can
serve as the "research" copy and the other as a "master" copy from which to
make additional "research" copies as needed.  This will cut down on the
handling of the original photographs, always a good idea.
