I am starting to transition from a hobby to a sole proprietorship and therefor starting out rather small. I won't need most of this information for a while, but it is handy to have it all in one place. It has all the forms in pdf format on a cd, and lists laws and regulations by state, so you know exactly what you need to do. It does still go over the different types of business, which I found vaguely annoying. One would assume that since you were buying a book on sole proprietorship that you would have already done that research and made your decision.
