Hi Kim,
I am taking ASL at my university, so perhaps you and I can help each other out. I have the book Learning American Sign Language by Humphries and Padden, it's okay but I would suggest just buying a book that has a dvd along with it, so you can see the signs. Go to google and put in ASL brower, one will come from Michigan State University which is a great site another one you might try is aslpro.com, I use this one when the other site doesn't have a word I need to practice on. I am hoping to get certified in sign language since my field of work is psychology and I want to apply for a job in San Diego that needs ASL interpreters. I am taking the first class now, and luckily for me the instructors, a brother (deaf) and sister team is willing to work with me in the summer time so I don't lose what I learned in class, until I attend their next course in the fall. I really love learning ASL, it's one language that I am mastering without any real problems and besides the brother who teaches the course is FINE!!!!! Anywho, I hope those sites help you out, please feel free to contact me, do you know someone who is deaf or is this something you need for employment or is it a hobby???
Good Luck
