I've found the following book to be an excellent reference source for most
modern methods of protein purification. It covers the major techniques and
has good discussion of the theoretical basis of the various
chromatographic and electrophoretic methods:

Protein Purification:  Principles, High Resolution Methods, Applications
ed. Jan-Christer Janson and Lars Ryden
VCH Publishers Inc, NY, NY 10010
ISBN 0-89573-122-3, published 1989

The book is a little sparse on simplified protocols, which conveniently,
the next two references (in the IRL Practical Approach series) supply:  

Protein Purification Methods:  A Practical Approach
ed. E.L.V. Harris and S. Angal
IRL Press
ISBN 0-19-963003-8 (softcover), 1989

Protein Purification Applications:  A Practical Approach
ed. E.L.V. Harris and S. Angal
IRL Press
ISBN 0-19-963023-2 (softcover), 1989

Hope this helps.
