In 2007 ICMA's Managing Small Cities and Counties became Managing Local Government Services, edited by Carl Stenberg and Susan Austin. It runs the gamut from meeting the challenge of change to the legal foundations of local government . . . to economic development, public works, emergency management, police services, and more. You can find it in ICMA's online bookstore or contact me if you need more info (email@example.com). Ian is right that between this book and Effective Local Government Manager, you'll have a full picture of the profession.
