Where once you were able to focus solely on the public you serve and the advancement of your career, you are now responsible for a multitude of people and all the issues they bring to the table as well as patrons and the building you work in. Weeee! While dated (2004) a lot of principles in this book will help the new manager with the basic things such as meetings, time management and how your role has shifted in the library culture. This is a lonely gig. As someone moving back into public service management, I looked at it as more of a refresher course in things I already knew. 2004, 211 pages.
