A good bio, and a bibliography of all his major poetry collections.
This page has a biography as well as great info on his nature poems (like "Big Poppy").
This website is all about Ted Hughes, and clicking-through is actually a surprising amount of fun, not to mention informative!
An interview with Ted Hughes from 1995.
A loosely academic article about the nature of Puritanism vs. violence in one of Hughes's poems. Great for a model analysis!
True scholarly article – difficult, but great in terms of what it means to be a "Romantic" poet. Also includes some thoughts by Hughes himself on the nature of poetry. [PDF]
Interviews, some readings – eight minutes of Hughes goodness.
Mostly audio, but also has a couple of neat, creepy images that go by in mosaic. Hughes is the one reading – definitely worth a listen.
A new-ish biography by Elaine Feinstein that attempts to chronicle, gently, the life of the often antagonized and controversial Hughes.
Another study of the life and works of Hughes, published in 2000 – with focus on the poetry more so than the life.
A dramatization of s the unsettling and complicated relationship between Ted Hughes and the poet Sylvia Plath. This movie stars Gwyneth Paltrow as Plath and Daniel Craig (a.k.a. James Bond) as Hughes.
This animated film is very loosely based on a famous Hughes short story by the same name.
