Drying books with canvas book jackets

I've been gathering information about drying methods for county
record books which have canvas (cotton) jackets.  What the vendors
say is:

    *   If water soaked books are vacuum dried with the pressure low
        enough that the water is sublimated, then the canvas will
        not shrink.

    *   If the vacuum drying involves a higher pressure, then water
        is in liquid form during the drying process, and the canvas
        jackets will shrink.

    *   If the books are air dried the canvas jackets will shrink.

Based on this information it would be best to remove canvas jackets
from water soaked books most of the time.  I'm interested in hearing
about real life results from people who have had water damaged
record books with canvas jackets.  Thanks,
