Reprints are wonderful for authors. You don't do any additional work, your story gets the chance to find more readers, and you get paid again. Two of my stories have recently been reprinted in big fat anthologies (the best kind). "Eliot Wrote" is included in LIGHTSPEED: YEAR ONE, along with stories by Stephen King, Ursula Le Guin, George R.R. Martin, and Bruce Sterling, among others. The anthology, perhaps self-evidently, features stories from the first year of the SF website Lightspeed, edited by John Joseph Adams.
The other reprint is ALIEN CONTACT, edited by Marty Halpern, which are stories of... well, alien contact. Authors include Karen Joy Fowler, Michael Swanwick, Jack Skillingstead, Neil Gaiman, and Stephen King. Mine is "Laws of Survival," one of my favorites among my own work.
Finally, loosely in the "reprint" category -- very, very loosely -- is a hilarious play I saw last night: THE COMPLEAT WORKS OF WILLIAM SHAKESPEARE. The three-person cast did indeed cover all the works, presenting the history plays as a football game tossing around the throne of England, the sixteen comedies in a hilarious mish-mash, OTHELLO as an "African-Italian homeboy rap," and HAMLET as an audience-participation scholarly analysis of Ophelia by a Freudian drama critic. If you ever get a chance to see this play, do so. I bet even the Bard would have loved it.
