I recently finished reading John Moore's Tribal Knowledge—a pretty darn good book of marketing ideas drawn from John's experience at Starbuck's. Lots of little nuggets to get you thinking about small improvements you can make in your marketing. He doesn't spend a lot of time developing any of the ideas in-depth, so it's a quick read.
Throughout the book John references several other books that are worth checking out. Along with the 40+ books listed in the Starbuck's Executive Bookshelf, John quotes from the following in the pages of his book:
The Macintosh Way by Guy Kawasaki (twice)
Built to Last by Jim Collins and Jerry Porras
The 22 Immutable Laws of Branding by Al and Laura Ries
Purple Cow by Seth Godin (three times)
Pour Your Heart in It by Howard Shultz (twice)
A New Brand World by Scott Bedbury (twice)
The Age of Paradox by Charles Handy
The End of Advertising as We Know It by Sergio Zyman
18 Immutable Laws of Corporate Reputation by Ronald Alsop
Servant Leadership and Servant as Leader by Robert Greenleaf
Journey to the East by Herman Hesse
The Abilene Paradox by Jerry Harvey
Lots of good stuff here. Pay close attention to Tribal Truth #4, a BrandStory favorite.
