Mycroft & Moran was an imprint of Arkham House publishers and was created in Sauk City, Wisconsin in 1945.
Arkham retired the imprint in 1982, but has recently allowed it to be revived by another small press publisher.
The name of the Mycroft & Moran imprint was derived from two characters in the Sherlock Holmes stories.
After the publication of The Solar Pons Omnibus in 1982, Arkham House retired the Mycroft & Moran imprint.
Later, the imprint was leased to publisher George Vanderburgh (Shelburne, Ontario, Canada), who revived it in 1998 with the publication of The Final Adventures of Solar Pons as part of the Battered Silicon Dispatch Box operation.
