Exploring the Horizons: Explorers and the Furthest Horizon edited by Gardner Dozois, SFBC May 2000 hardcover, science fiction anthology omnibus. Collects 2 previous anthologies. 916 pages. Cover by John Berkeley.

Put together by one of the best editors in the genre, an eleven-time Hugo Award winner for editing. Now sadly gone.

I picked up a copy after I saw this reviewed on the Black Gate blog, and later on George Kelley’s blog. Exploring the Horizons combines two separate collections, Explorers and The Furthest Horizon, bound together in this omnibus edition.
