Thanks for the answers.Since the posting, I found a book for sale at our local library for about $US.60 called "Beginning the Five-String Banjo" by Jerry Silverman. He describes the technique very clearly and has a lot of traditional songs in it.
Nonetheless, he never uses the term "claw hammer", so I am glad for the descriptions.
Now that I have a book Jon, all I need is a banjo! I will start with soft-soled shoes.
