Web
Style
Guide: Basic Design Principles for Creating Web Sites,
by
Patrick J. Lynch and Sarah Horton. A unique resource
that "combines
traditional editorial approaches to documents with
graphic design,
user interface design, information design, and the
technical authoring
skills required to optimize the HTML code, graphics, and
text
within Web pages." Available both as a softcover book
and
online at http://info.med.yale.edu/caim/manual/intro/introduction.html

A great site for good advice that's appropriate for
nondesigners.
I'd highly recommend any of her books, too.
