Accessing Online Language Resources Provided By the University of Chicago.

WJG (10/08/06). The University of Chicago (http://machaut.uchicago.edu ) provides a useful portal to a large number of language resources amongst which are the Webster Dictionaries and Roget's Thesaurus (made available by the Gutenberg Project). Naturally, as an Englishman I prefer the Oxford English Dictionary, however, as I don't have a copy (who does?) the Webster dictionary is a fine alternative. Indeed, the placement of etymological notes at the head of each entry is precisely what I'm interested in. Rather than searching through the portal itself, I hacked up a few lines of code today to enable me to add some query buttons to my Tk apps. Good ol' Tcl/Tk!

To use the demo, type in some text, select the word that needs to be queried and click on "W" for a Webster Dictionary search or "R" for Roget's thesaurus. Some further enhancements could be made, any comments warmly welcomed.
