Freeze-drying herbarium specimens

From: W. Alexander Flinn <|alexflinn>

We are about to treat some water damaged herbarium specimens. The
specimens are mounted in books and the assemblage has become wet.
Has anyone freeze-dried any similar objects? and if so what problems
were encountered? For instance, were the specimens friable after
treatment? were the pages easy to separate after treatment, etc.?
