Tomorrow Times Seven (1959) - a collection of stories by Frederik Pohl. Many of these can be found in other Pohl collections - but most of them are British (with no American editions.) Five stories are from Galaxy, where Pohl was a regular - enough so that he took over editing that magazine in the Sixties.

The Haunted Corpse
The Middle of Nowhere
The Gentle Venusian - (original title= "The Gentlest Unpeople")
The Day of the Boomer Dukes
Survival Kit
The Knights of Arthur
To See Another Mountain

These originally appeared in the span of 1955 to 1959 - 5 in Galaxy; and one each from Future SF and Magazine of F&SF.
