Lisp Help

I want to buy a book to learn autlisp. So far I've found some good stuff online and I've downloaded some lisps and reversed engineered them. However I really need a good book to learn it properly. Does anyone have any suggestions as to a good book? I've searched amazon and some some book. Many seem outdated. I just don't know what to get. Thanks in advance.

Also one more question.

What is VBA and how is it useful?

Re: VBA (Visual Basic for Applications) and AutoDesk products. Start your education here.

Check out this thread too while you're at it. Note that AutoDesk is considering moving away from using VBA in the future.
