The purpose of a concordance is to show the places in a document or a class of documents where each principal word may be found. Typically, the immediate context of a word is exhibited, as well as its location. How the concordance is to be organized, and for what use, will vary from user to user and from occasion to occasion. Until recently, concordances were manually prepared, perhaps the most familiar being those of the Bible. 1 Over the last decade, computers have been used to generate various types of concordances. Computer-generated concordances of the poetry of Matthew Arnold and, more recently, of W. B. Yeats have been described by Painter and Parrish. 2,3 KWIC (Key Word in Context) indices 4 have become routine.
