Foreword to the Third Edition ~ts naro to t)elmve that 1996 marks the 30th anniversary of the infa- mous White Paper, the document that introduced the modern concept of Emergency Medical Services. One could argue that EMS actually began in biblical times when the Good Samaritan stopped to render aid. However, hundreds of years would then pass before the National Acad- emy of Sciences published the White Paper in an attempt to formalize the process of rendering care to trauma victims.

The timeless nature of Streetsense makes it at once abook for the novice EMS provider as well as for the seasoned veteran. I have always been fascinated when I have picked up my tatteredcopies of the first and second editions how Streetsense has meant dif-
