Not familiar with this one. Is it published by the same people that publish all the other idiot's guides, ie. chemistry, trigonomotry, etc?
I have a very old book (about 20 years) called "Lou Fant's American Sign Language Phrase Book." I still use it from time to time, and would highly recommend it.
there are some opinons on that page.
I just got a new books called - talking with your hands listening with your eyes. its more of a refrence book with info about important topics relating to Deaf and hh. Very good.
