Resource for 17th Century English Literature
If you're wanting some background information on English literature from the time of Beaumont and Fletcher, Webster, and Donne, here's a good site to check out: Early 17th Century Literature. The site categorises the Metaphysical Poets and the Cavalier Poets (listing them and giving a brief introduction to the terms). There are also pages devoted to many of the writers of the time, complete with quotations from their work, bios, a list of their writings, and lists of critical works about them. Finally, there are links to further resources about this time (such as writings about the politics of the period, music, the plague, and so on). Definitely worth a look.
