The "No Frills" series was a collection of genre fiction paperbacks published by Jove Publishing in 1981 with plain covers, no author names, and maximally pulp plots. From Weird Universe:

Terry Bisson, who was one of the instigators of this project, reports:

Mystery was written by Clark Dimond, a men's mag editor/writer who also wrote for comics. The Romance was written by Judy Coyne (former Glamour mag editor) nee Wederholt The SF was written by John Silbersack, SF editor and now an agent. The Western was by Vic Milan (SF author) We were working on a No-Frills Besteller (by me) and A No-Frills movie (by film critic David Ansen) when the series was dropped. My partner selling the series was Lou Rosetto who went on to found WIRED magazine.
