Macsyma vs. Maxima, book



I am looking for a book on Calculus using Maxima. I
came across this  link
http://www.math.utexas.edu/pipermail/maxima/2003/004000.html
which is 2 years old. it was helpful in suggesting 2
books;

Computer-Supported Calculus
by Robert P. Gilbert, Adi Ben-Israel
ISBN: 32118-2924-5

Macsyma Tutorial for Calculus, by Richard N. Fell,
Jones and Bartlett Publishers, Sudbury, Massachusetts,
1998

2 years have passed and before going and buy them I
wanted to drop a post asking for suggestions.

thank you
