Jerome Bixby: Summer 1950 – July 1951. Malcolm Reiss: September 1951 – January 1952. Jack O'Sullivan: March 1952 – Summer 1955. Planet Stories was a pulp-sized magazine for all of its 71 issues. It was 128 pages for most of its existence, and was priced at 20 cents. With the November 1950 issue the page count was cut to 112, and the price went up to 25 cents. The page count was reduced to 96 for one issue in March 1952, but then returned to 112 until Summer 1954, when it was again reduced to 96 pages for the last five issues. Planet began as a quarterly. A brief attempt was made to switch to a bimonthly schedule in 1943; a March and May issue appeared, but the next issue was titled Fall 1943, inaugurating another quarterly period. The Fall 1950 issue was followed by November 1950, and this began a bimonthly period that lasted until May 1954, which was followed by a Summer 1954 issue. A quarterly schedule resumed until the end; unusually, the winter issue that year was dated Winter 1954/55, rather than with a single year. The volume numbering was consistent throughout the magazine's publication, with five volumes of 12 issues and a final volume of 11, but there were three errors in the volume numbering printed on the spine (though not on the masthead): issue 5/10 was given as 5/8 on the spine; issue 5/11 was given as 6/3 on the spine; and issue 6/11 was given as 6/12 on the spine. A British reprint edition appeared between March 1950 and September 1954; the issues were numbered but not dated, and were heavily cut, with only 64 to 68 pages. There are twelve issues known; a thirteenth has been rumored but not seen by any sf bibliographers. The publisher was Pembertons, though some sources indicate that Streamline Publications was the publisher of the first issue. Issues 7 and 8 of the British edition also contained nonfiction material reprinted from Startling Stories and Thrilling Wonder. A Canadian edition was published by American News Co., from Fall 1948 to March 1951 (a total of twelve issues); these were identical to the corresponding U.S. editions. Related publications In the summer of 1950 Fiction House launched a companion magazine to Planet. It was titled Two Complete Science-Adventure Books; the policy was to print two novels in a single magazine. It
