As a copy photographer who makes slides from illustrations in books, I
see frequent use of Post-it notes for marking. I don't think Geoffrey
Brown goes nearly far enough in urging caution with so-called
"removable" adhesives and archival materials. When I remove a Post-it
from a glossy paper, then place plate glass over the paper to hold it
flat for photography, a very substantial smudge of greasy adhesive
transfers to the glass from the place where the Post-it had been stuck.
Also, I have encountered some Post-it-style notes which were very
difficult to remove even from paper in good condition, because the
adhesive was unusually strong.
