In concordance with Jeanne Eichelberger's experience, a few years
ago I conducted a CAP survey for a museum which stored records and
film in fire-proof filing cabinets.

I put my data logger into one of the drawers and went to lunch. When
the data were downloaded it was clear that the %RH inside those
particular filing cabinets was approximately 15% higher than the
ambient conditions.

My recommendation to the museum were substantially the same as Ms.
Eichelberger's.  Open the drawers weekly and leave them open all
