Running 30 volumes under two successive editors, the UK series
New Writings in SF remains the longest-running series of original anthologies. The series began in 1964 under editor John Carnell, who had edited UK magazine
New Worlds before turning it over to Michael Moorcock earlier that year. Like Carnell's
New Worlds, his
New Writings was solid and conventional compared later original anthology series, somewhat the UK counterpart of the later years of Campbell's
Analog. Carnell's introduction to the first volume cites the limited appeal of the genre magazines (of which there were then many fewer than there had been in the heyday of the 1950s) and the expansion of hardcover and paperback book publishing. He also promises new styles, ideas, and writers.
The UK series issued up to four volumes per year through its entire run. In the US Bantam republished the first several volumes intact, though at longer intervals, beginning in 1966, running through volume 6 in 1971, a full five years after that volume's UK publication. As if to catch up, the last three Bantam volumes, 7 through 9, take selections from multiple UK volumes: US 7 from UK 7 to 9; US 8 from UK 10 to 12; US 9 from UK 12 to 15. Then Bantam abandoned the series, perhaps a consequence of Carnell's death in 1972.

In the UK the series continued under editor Kenneth Bulmer and for a different publisher, with volumes 22 to 30. Bulmer was perhaps a bit more adventurous than Carnell had been; e.g. publishing triplets of vignettes by Brian W. Aldiss, in six of his volumes.
