Foley, van Dam, Feiner and Hughes, Computer Graphics Second Edition,
have 4 pages on NURBS and then point off to other sources. 

If you really want to understand NURBS you need to work through splines
and spline surfaces. There are two ( probably many more ) books for this:

Farin, Gerald, Curves and Surfaces for Computer Aided Geometric Design,
Second Edition, 1990, Academic Press, ISBN 0-12-249051-7. This book
covers Rational Bezier and B-spline Surfaces (NURBS) briefly. It has
good bit on rational curves.

The Killer B's book - Bartels, Beatty, Barsky, Introduction to splines
for Use in Computer Graphics & Geometric Modelling, 1987, Morgan Kuafman
Publishers, ISBN 0-934613-27-3. This book does not get to rationals - but
might be worth it to get two views on the basics.

If anyone knows of a paper that explored NURBS from a PHIGS perspective
I'd like to hear about it.
