one of my favorite books for beginers is "Production Fly Tying" by AK Best......dont be scared off by the title, its a great book that gives exacting step by step instructions for different style of flies and has an extensive description of tools needed.
a great book for a neophite or a veteran tyer.
"Fishing is the most wonderful thing i do in my life, barring some equally delightful unmentionalbles, and not disregarding gluttony and booze. It's in the top five." -Jim Harrison
