The Police Executive Research Forum was established in the US in the 1970s and provides a wide-range of publications and research reports related to debates addressed throughout this book. The Forum’s website is: http://www.policeforum.org/

The College of Policing website provides a similar range of material and is particularly useful for those interested in learning more about the professionalization debate: www.college.police.uk. The Society for Evidence-Based Policing web-site also contains useful information on this strategy: www.sebp.police.uk/

There are a number of useful blogs and web-sites offering debate and opinion on contemporary policing. Among these are the Police Oracle site www.policeoracle.com/ and the British Society of Criminology Policing Network blog http://bscpolicingnetwork.wordpress.com/pn-blog/
