They can be read on-line and they can also be downloaded for future reading. To access that material, link up to the Web-site mentioned by Camilla: http://www.parkinson.org . When - after a long wait - the home-page finally gets loaded, check the SITE DIRECTORY on the left of the screen; click LIBRARY, then click ON-LINE PUBLICATIONS. Ben Winter
