On this auspicious (or arguably inauspicious) date, I cannot resist a wander into the works of The Bard. For those of you with the same penchant, try the Oxford Shakespeare at Bartleby.com . You can view each work, or search what is known as a Concordance. You type in the words and find in what play or sonnet your words appear. Using this concordance I now know that Julius Caesar ignored the Soothsayer to his peril in Act I, Scene II.
There are many other Concordances available on the Web. Try the Hyper-Concordance for one site that has many works and authors collected.
