Public Administration

I am looking for reputable sources of information on Public Administration as a theory and a practice. Names of books, authors, blogs anything of that nature would be appreciated. I am new to the whole area of study so I am looking for somewhere to begin.

Thanks

Journals:
Journal of Public Administration Research and Theory

Journal of Policy Analysis and Management

Journal of Public Policy

Books:
Theories of the Policy Process (Sabatier, ed)

Agendas, Alternatives, and Public Policies (Kingdon)
