There are many good books about marketing.

Anything by Seth Godin. Anything. You should have at least one Seth Godin book in your library including any of his free e-books like Bootstrapper’s Bible, Flipping the Funnel, or the one that started it all: Idea Virus.

Tom Peters is famous for In Search of Excellence. But its more strategy than marketing.  Re-Imagine!

You can’t be in sales without a book from Jeffrey Gitomer, a great sales trainer. Try either The Sales Bible or The Little Red Book of Selling
