I received an email from the publisher of Nimble Books, which is the company that is producing the The Handbook of 5GW: A Fifth Generation of War? for sale. Â Currently there are around 21 forthcoming Nimble Books, with the Handbook in place # 8. Â Nimble averages actually publishing (getting out for sale) four-to-six books a month, meaning that the Handbook is expected (knock on wood!) by Christmas.
