Alan Richmond built NASA's first astrophysics information system on the World-Wide Web (WWW), as a principal systems engineer and group leader at the Goddard Space Flight Center. He specialises in transatlantic projects; HTML and CGI training; advanced WWW applications; and web searchable databases ranging from very simple tabular searches through to more complex relational databases. He presents advanced tutorials at DCI's WebWorld. He is creator and curator of the The Web Developer's Virtual Library which has a searchable database of some 1000 annotated URLs. He has built software for several international scientific research projects, such as the the NASA/ESA Hubble Space Telescope. Alan gratefully acknowledges the collaboration of Mark Cox at the University of Bradford in England, with some parts of this tutorial.
