Paratime Series
The Paratime series written by H. Beam Piper consists of several short stories, one novella, and one novel; they deal with an advanced civilization that is able to travel between parallel universes with alternate histories, and uses that ability to trade for goods and services their own, exhausted Earth cannot provide. Specifically, the Paratime series deals with the Paratime Police, the organization that protects the secret of paratime travel.

Famous quotes containing the word series:
“As Cuvier could correctly describe a whole animal by the contemplation of a single bone, so the observer who has thoroughly understood one link in a series of incidents should be able to accurately state all the other ones, both before and after.”
—Sir Arthur Conan Doyle (1859–1930)
