"Digital Halftoning", Robert Ulichney, The M.I.T. Press, 1987,
ISBN 0-262-21009-6.
"Based on a Ph.D. thesis at M.I.T. in 1986 entitled 'Digital Halftoning
and the physical reconstruction function'".

My copy cost $35, from the Stanford University bookstore.

It is near state of the art; the only algorithms that will do better are
closely held trade secrets. 

Note that this work treats only binary (bi-level) monochrome halftoning;
multilevel and color halftoning are treated only in passing.
