If you're serious about copywriting then Breakthrough Advertising book by Eugene Schwartz is a MUST READ!
In my humble opinion I think that it's so advanced that this should not be the
first book you read on copywriting. Try Kennedy's Ultimate Sales Letters and
Joe Sugarmans Advertising Secrets of The Written Word.
Also:
Tested Advertising Methods - John Caples
Confessions of an Advertising Man /Ogilvy On Advertising - David Ogilvy
Scientific Advertising - Claude Hopkins
Influence: The Psychology of Persuasion - Cialdini
Web Copy That Sell -Veloso
Well, that's a good start ...
Each book has it's strength, for example Caples is very strong on writing
headlines, so read them all.
