The Milton reading room, maintained by Dartmouth College, is the best website for Milton's poetry on the web.
JohnMilton.org is another excellent website for Milton's poetry and prose, and features audio recordings of many of Milton's poems.
The Poetry Foundation has the best biography of John Milton that I'm aware of on the web, which also includes a detailed analysis of Paradise Lost and an extensive bibliography.
The Milton Quarterly, published by John Wiley and Sons, presents current studies of Milton's poetry and prose.
Milton Revealed: "a collaborative project to collect audio-visual materials related to John Milton and his work, to re-examine his relation to theatricality, and to develop teaching approaches to Milton that use performance across a variety of media."
JSTOR: Many repositories of academic articles charge high fees, fees absolutely commensurate with the services they provide, but which have the unfortunate side-effect of denying access to enthusiastic amateurs such as myself. One repository, JSTOR, has found a happy compromise. They allow private individuals to place a very limited number of articles on a personal bookshelf. For private individuals such as myself, they are a godsend. Thanks JSTOR!
Milton's poetic milieu: an excellent reference for the poetry of Milton's era.
Theocritus' Idylls: a similarly excellent reference for the Greek model upon which Milton based Lycidas.
Virgil's Eclogues: and one more excellent reference, in this case to the Latin model for the bipartite structure of Milton's poem (see the third clue under "Past Clues" for more information on Lycidas' bipartite structure).
For those who came to this site in search of new riddles, the following are some sites which seem to have good collections, including a couple specifically targeted toward children:
Research Maniacs (boasting they have the world's hardest riddles - they haven't been contacted about Lycidas yet!)
And more to come!
HalloweeM - Halloween Mensa-style - is a party you'll want to attend if you can make it! This event has a special place in my heart, because a couple of years ago I presented my complete reading during this convention. It has tens if not hundreds of talks every year, and the inimitable WeeM costume parade, and a game room, and tournaments, and other activities (including special programming for kids), all taking place on the Thursday through Sunday closest to Halloween. A yearly highlight for the many who attend!
Mensa's International website provides information about this organization around the world.
American Mensa's website provides information about the 57,000+ members and their activities in the United States.
