I borrowed two books from a lady at the support group I go to. I can't decide which one to read first. The two books are The RDI Book. by Steven E. Gutstein,PH.D or The Picture Exchange Communication System training Manual by Lori Frost and Andy Bondy.
I'm not sure if I could read them both simultaneously. Which one would you read first and why?
