You can find lists of my papers in several places on the Web. The official repository of information and full texts is at the Edinburgh Research Explorer, the research repository of the University of Edinburgh.
Since my publications span many disciplines, the main list of my publications with citations is on the one and only Google Scholar. You can also find links between my papers and citations thereof on Scopus and on the ACM Digital Library (Edinburgh affiliation, Bonn affiliation)
I am on two academic networking and paper-exchange web sites, which I use to keep in touch with colleagues.
