Many resources are available on the World Wide Web (web for short) and some selected resources are available on CD-ROM. The advantages of the latter are immediate local availability and hence speed of access, but they lack the flexibility of the web, and typically cost real money. However, the disadvantage of referring to materials on the web is that they are not under one's own control; hence information may be out of date, and there can be no guarantee of accuracy. A partial solution to this problem is to construct one's own web page in the form of a ‘portal’ to relevant web sites, and only to link to those sites which have been created by colleagues whose work one trusts/admires. I plan to keep my site active for the immediate future, at the address http://venables. asu.edu/grad/appweb1.html which is accessible from my home page http://venables. asu.edu/index.html as Web-based resources. The initial appearance of this page is shown in figure D.1 below. The web-teaching experiences which lead to the construction of such pages are described by Venables (1998).

Potentially relevant resources on CD-ROM include the following:

1. The NIST Surface structure database. Details are accessible via my page on data bases at http://venables.asu.edu/grad/appdat1.html
