Through the good offices of the Primo Pdf freeware I have been able to produce Adobe pdf copies of most of my publications. The pdfs are available, as before, by clicking on the link next to the reference. Papers are also available as web pages. Some of them may take a while to load as I tend to use a lot of pictures ;-)
If you have any problems with these, please contact me
Clicking links will open new web browser, so if you have a popup blocker you may have to make adjustments, or copy down the link……………………
