When you really love a book, the short biography of the author on the jacket is not likely to satisfy your curiosity. But even if you could have a talk with the author, what would you ask? Canadian Broadcasting Company reporter Stephen Banker knows what to ask, having interviewed more than a hundred authors for various radio programs. And he sells his taped interviews ($9.95 reel-tureel, $10.95 cassette) so you can get to know the likes of Kurt Vonnegut, Woody Allen, Tennessee Williams, John Updike. He has two Nobel Prize winners - Pablo Neruda and Saul Bellow. And he covers interests as far-flung as Sesame Street (a delightful music-filled interview with composer Joe Raposo) and Gloria Steinem. He has an extensive series on black studies (Adam Clayton Powell Alex Haley), sports (Muhammad Ali, Willie Mays), art (Charles Eames, Saul Steinberg, Joseph Hirshborn), and entertainers (Emmer Kelly Jr. Zubin Mehta). The collection, called Tapes for Readers, is continually expanding. And once you get the list, you are likely to find somebody there whom you want to get to know better.

Tapes for Readers. 5078 Fulton St. NW, Washington, D.C. 20016. $9.95 reel-to-reel, $10.95 cassette. 362-4585.
