Computer preparation of a poetry concordance
A concordance is an alphabetical index of the words used by a major writer, or group of writers, showing each word in its context. It is one of the basic research tools for scholars in the Humanities. Concordances are very useful in studies of language, vocabulary, and the history of ideas in literature and philosophy. Use of a concordance is probably the only way to interpret critically, or sometimes even to understand, a symbolist writer. It can also be used to help determine the age or even the author of a piece of anonymous writing.
