"When John died we all missed him quite deeply. There was a feeling among the people who were both his authors and friends that there should be some sort of tribute. It was decided that a memorial volume would be in order, stories written specially for the volume by the writers who worked for John's magazine," Harry Harrison, introduction to "The Mothballed Spaceship," The Best of Harry Harrison.
