[Air-l] neat indexing system

I've not run across this method before, and thought folks on this list might enjoy puzzling over it. http://www.ugcs.caltech.edu/~harel/lyrics.html The website contains a collection of texts (popular song lyrics). Having made a selection from the contents, you can click on various linked words within the text (not all possible words are linked). That action triggers (a) enumeration of the texts in the library that contain the target word, and (b) a hyperlinked index connecting you back to those available texts. Each instance of target word use appears in the index list. It looks to me like quite a bit of HTML page generation is done automatically via scripting on the server side.
