M=SF is a range of science fiction and fantasy novels from the Dutch publisher Meulenhoff. The range was started in 1967 and continues to this day (Uitgeverij M continued the range in 2001 and Uitgeverij Mynx since 2006).
Although the bulk of the titles are translations from the English language works there are several original Dutch language novels in the range as well.
