From time to time this question comes up. Most times the replies are about strategy, marketing or the memoirs of a billionaire.
How about this time books that provide more of a reference library. The "how-to's", the theory or simply your accounting 101 textbook.
As an example, two of Proformatives contributors (I'm sure there are more) wrote books.
"Redesign to Turnaround Underperforming Small and Medium-Sized Businesses" b Regis M. Quirin
"Guide to CFO Success" by Samuel Dergel.
What's in your library and did you really read it.
