Here's an useful resource for researchers of all walks: UNZ.org, which is billed as "A Free Website for Periodicals, Books, and Videos" provided for "purposes such as criticism, comment, news reporting, teaching, scholarship, and research."

The site is well-organized and easy to use (if not looking a little bit like the Internet circa 1996). A quick survey of the 1930s and 40s delivers works by W.H. Auden, C. Day Lewis, Louis MacNeice, and Stephen Spender.

And what of Henry Reed? Turns out there's lots! Including Reed's answer to "The Cost of Letters" questionnaire in the September, 1946 issue of Horizon; G.D. Klingopulos' review of A Map of Verona in the December, 1946 Scrutiny; the first appearance in print of Reed's poem, "The Auction Sale," from the October Encounter of 1958; and Geoffrey Strickland's review of Reed's collected Lessons of the War in the May, 1971 issue of Encounter. Plus, dozens of other mentions of Reed in other journals and periodicals to be sieved through.

Give your favorite author- or poet-of-interest a search, yourself.
