[2] Some of Weber's first jobs within the writing/advertising world began after high school when he worked as copywriter, typesetter, proofreader, and paste-up artist.

[4] Weber used the Starfire universe as a setting for short stories that he wrote for the company's Nexus magazine, and he also wrote the Starfire novel Insurrection (1990) with Stephen White after Nexus was canceled; this book was the first in a tetralogy that concluded with their final collaboration, The Shiva Option (2002), which was included in The New York Times Best Seller list.

[5] Weber was influenced by C. S. Forester, Patrick O'Brian, Keith Laumer, H. Beam Piper, Robert A. Heinlein, Roger Zelazny, Christopher Anvil and Anne McCaffrey.

[2][6][7] Weber's novels range from epic fantasy (Oath of Swords, The War God's Own) to space opera (Path of the Fury, The Armageddon Inheritance) to alternate history (1632 series with Eric Flint) and military science fiction with in-depth characterization.

[4] Weber is a lay speaker in the United Methodist Church, and he tries to explore in his writing how religions (both real-life and fictional) can be forces for good on the one hand, and misused to defend evil causes on the other.
