Chuck, it's true you can go to Amazon to find what books they have on
CS.  That is not the same as a recommendation, as all books are not
equal.  I was hoping someone would answer Becky as I would like a
recommendation also.  I did go to Amazon and I ordered one of the books
at random with no idea of which one was best. Books are so expensive to
guess at.  Those of you who know the field know the best works and
authors, just as I posted references for biomagnetics.  John
