Workforce 2.0: Free Agent Nation by Dan Pink* covers the changing nature of the labor markets

Thinking 2.0: Whole New Mind by Dan Pink covers the styles of thinking that are likely to dominate

Marketing 2.0: Groundswell by Charlene Li and Josh Bernoff, which bumps Naked Conversations by Robert Scoble and Shel Israel* to second place. Covers the impact of blogs on marketing and other market-facing roles.

Intelligence 2.0: The Wisdom of Crowds by James Surowiecki is the Bible of crowdsourcing, but usually used to analyze consumer market phenomena like Wikipedia more than enterprise equivalents.

Law 2.0: The Future of the Internet-And How to Stop It by Jonathan Zittrain. The definitive treatment of the legal and IP culture. Something by Lawrence Lessig also probably belongs as a runner-up. Any nominations?

Attitude 2.0: The Age of Speed by Vince Poscente manages to grab a small but very important slice - the acceleration-of-everything aspect

Organization 2.0: The somewhat creaky and rusty The Cathedral & the Bazaar by Eric Raymond* remains the best treatment of Open Source models of organizing work.

Technology 2.0: The Big Switch by Nicholas Carr covers what is happening to the underlying technology. This one was hard for me, since I wanted to make it a horizontal ‘circle'' layer but couldn''t justify it. It remains a pizza slice, albeit a big and important one.

Geography 2.0: Who''s Your City by Richard Florida, bringing to a conclusion his long exploration of the creative class, explores the new nature of physical geography. It is a very broad pizza slice - another one that almost made it as a foundational broad book.

Demographics 2.0: Generation Blend by Rob Salkowitz is the best treatment I''ve seen so far of the demographic aspects - 4 generations in one cataclysmic time

Economics 2.0: Chris Anderson''s Free (currently a Wired cover story) is going to be a bestseller and will likely be the classic on the economic aspects of World 2.0.

Innovation 2.0: Open Innovation by Henry Chesbrough has been the classic on enterprise innovation 2.0 for a long time, but could now be threatened, since its coverage is beginning to be slightly obsolete. Write another Henry (Open Business Models didn''t cut it!)

Management 2.0: Competing on Analytics by Tom Davenport and Jeanne Harris is a sleeper hit that the more iPod-happy consumer end of the literature hasn''t paid much attention to - it is fast becoming the bible of data-driven management for an era of data abundance (data scarcity has been the dominant unwritten assumption of much management writing pre-2000). It is likely to be supplanted by a broader book though.

Market 2.0: The Long Tail by Chris Anderson* is the anchor text of modern market strategy for a world driven by hyper-personalization and customization for niches.

Work 2.0: The Dip by Seth Godin is seriously important for a key reason - it is not packaged as such, but it is actually the best treatment of what to do about the attention-scarcity economy, even though that is not the book''s focal point. It squeezes out Davenport''s more direct treatment, The Attention Economy.* It is, in a sense, also a sideways-antithesis to The Long Tail.

Brand 2.0: Made to Stick is probably the only credible treatment of the nature of viral information ''stickiness'', but will likely be displaced.

Career 2.0: And circling back to Dan Pink, Johnny Bunko is going to be the career workbook of the go-getters in Gen Y.
