The Gollancz Classic SF series issued between 1986 and 1987 brought together some of the best works of science fiction from the 1950s, 60s and 70s. It was a precursor to VGSF Classics (1988-90) and the SF Masterworks series published by Orion through their Millennium and Gollancz imprints beginning in 1999.

The purpose of this challenge is not necessarily to read the specific edition of the series, but rather to engage with the books that were selected for the series.
