Future Boston (1994) - a "shared-world" anthology written by a small pool of authors contributing several stories each - edited by David Alexander Smith. A few of these had previous magazine appearances 1988-1991: (4) in Isaac Asimov's, 1 each in Analog, Aboriginal SF., and Figment. A related novel is In the Cube by David Alexander Smith (which I've read and can recommend.)
