The March 2011 issue of The Writer has a brief article about The Paris Review posting its famous author interviews online. The archive is complete to date, and includes interviews with such famous writers as Ernest Hemingway, Joan Didion and William Faulkner, among many others.
According to the article, the literary journal, founded by a group of editors in 1953, lacked the money to attract top writers to contribute, so they decided to interview the writers they admired the most. They published the interviews in the journal. What a creative way to interest potential contributors in your publication!
