Underwood–Miller Inc. was a science fiction and fantasy small press specialty publishing house in San Francisco, California, founded in 1976. It was founded by Tim Underwood, a San Francisco book and art dealer, and Chuck Miller, a Pennsylvania used book dealer, after the two had met at a convention. Underwood and Miller chose to begin with a first hardcover edition of The Dying Earth by Jack Vance. This was a classic fantasy novel never done in hardcover. Both Donald M. Grant, Publisher, Inc. and Mirage Press had tried to publish The Dying Earth but had failed to obtain the rights.
