The Waring Library has a number of medical (histology, etc.) slides
in our collection and we have not considered remounting because we
feel that it definitely effects the historical aspect and
significance of the slides.

Ours have yellowed, too, but I have not noticed a worsening in the
yellow over the 12 year period that I have been observing them. We
have tried to give them a more stable environment than they had in
their previous home and we hope that has helped.

However, I will add that one of the primary reasons we have not
considered remounting is economic (not enough staff time or money to
hire an outside conservator).

What use will be made of the slides? Would the
researchers/scientists/botanists prefer to see them in their
original form or remounted?

Thought: could you remount the cracked ones and have something to
