The Theory of Strings: A Detailed Introduction
A longer and more detailed article of mine, still non-technical but somewhat more demanding and perhaps better suited to science students or practising scientists (not necessarily physicists). It might also repay patient reading by a lay person, but I won't swear to that.

Elements of String Theory
An article that I co-authored with Atish Dabholkar and Spenta Wadia when the three of us were organizing the Strings 2001 conference. This was used to inform the press and the general public, who showed immense interest in the conference.

Website on the PBS movie, based on Brian Greene's book of the same name.

The "Official" String Theory Website
A fascinating production, with a variety of information on string theory, and a lot of other stuff, presented in a colourful environment with pictures and sounds. I'm not quite sure what's "official" about this site, though...

New Ways to Make Old Strings
A colloquium I gave at the University of Louisville, Kentucky, in September 2002 to an audience of physicists. This was broadcast on the Access Grid, a video conferencing facility for scientific institutions - or, as the maintainers like to call it, "the ensemble of resources that can be used to support human interaction across the grid"..
