This hypermedia document is an attempt to define and connect some of the main concepts of generic programming, a relatively new approach to computer programming. It is also intended as an illustration of computer-supported concept development and knowledge representation. Thus the document is written as interlinked text pages, which, together with WWW browser capabilities, put the concepts in a more accessible (and malleable) form than a traditional linear presentation could do. The document is an example of what I call a concept web, in which the main content of Web pages is definitions and discussions of the concepts of some particular subject area, and the links between the pages include ones that show concept refinement relations. In the print version of the document, hypertext links are replaced by page references.
