Books, books and more books

I took a step back the other day to take a look at everything that I have read while building Pixmonix. The list is very large. This includes book on starting and running a business, technical books (e.g., on building websites, using photo and video tools) and managing people and processes within an enterprise. When I add in the books and magazines that I have read for fun, it is kind of ridiculous. Over the next several weeks, I will try to summarize what I have read and offer my limited insights into what is worth reading.

What have you read while establishing your business that you found particularly useful?
