Bartleby is a great resource for reference and literature, or as they say, "great books online." It has over 370,000 web pages, which includes over 86,000 quotations, and over 10,000 poems, both of which are the largest collections on the web. Also included are audio (word pronunciation), and thousands of illustrations of maps, flags, and anatomy. The front page has a daily biography, definition, quote, and poem, which you can also get via email. Yahoo Education uses Bartleby data.
