What exactly is the purpose of preshrinking in hot water? I do it
because the book told me to. I rarely develop a print in anything above
say, 80 degrees.

Preshrinking is an attempt to make the paper dimensionally stable so
that multi-layer processes will register properly. I have found that it
doesn't always work with every paper I use - some are stubborn and
refuse to stay dimensionally stable anyway. Most people use rag papers
which are made of cotton; when soaked in hot water, the fibres shrink
and stay that size (theoretically).It is a miserable experience to find
that your image and negative are different sizes halfway through a
print.....
