I think this is an interesting topic. Most likely it's been done already. Anyway, here's my list:
- Monk and the Riddle- Randy Komisar (You HAVE to read this, it puts it in the right perspective. Randy is a genius)
- Paypal Wars
- Founders at Work- Jessica Livingston
"Best Practices"-type books that cover the tools and technology the startup is using, whether its Textmate, Unix, Subversion, whatever. Becoming more efficient is never a bad thing.
I'd also add books on management and dealing with people:
- The Art of Speedreading People - Tieger
- Behind Closed Doors - Rothman, Derby
- The Mythical Man Month - Brooks
- Most if not all the books on Joel Spolsky's "MBA Curriculum":
