Off the Main Sequence

by Robert A. Heinlein

A collection of 27 short stories by American writer Robert A. Heinlein, including three that were never previously collected in book form. The title is a play on the astronomy concept off the main sequence, and refers to these stories not being part of Heinlein's Future History.
