As can be seen, poems have been steadily decline and are now rare in F&SF. Cartoons, on the other hand, have increased dramatically in F&SF, especially after Gahan Wilson's streak of one cartoon in each issue from April 1965 to October 1981 ended (for a total of 204 of his cartoons).

Book Reviews
Book reviews first began in F&SF in its 2nd issue, Winter/Spring 1950. They mostly stayed with one per issue, for the most part, until the 1990s, when it became common to have two or three per issue, and sometimes four. Early book reviews by Boucher & McComas tended to be one or two sentences per book, really a listing of books in the genre that had been published recently. Then came real reviews by a series of reviewers (Damon Knight, Alfred Bester, Avram Davidson, Judith Merril, Joanna Russ, Algis Budrys, Orson Scott Card, Charles de Lint), with the occasional guest reviewer adding their words. Often these reviews were begun with an essay on an author or publishing trend, or the perennial essay on what is the difference between fantasy and science fiction. In 1966, there began to be the occasional issue with two book reviews, one being an in-depth exploration of two or three books, the other review offering shorter briefs of more books. In the 1990s, with the explosion of published books, an in-depth review column was followed by several shorter review columns, therefore covering as many books as possible. In June 1998, a new column, "Curiosities," reviewed older books that deserved attention and that might be found in used bookstores. (It was preceded by a series of columns by Mike Resnick, "Forgotten Treasures," between February 1997 and March 1998, that served the same purpose). The following chart shows the number of book reviews per decade, along with the number of issues in that decade:

Book Reviews	1949, 1950s	1960s	1970s	1980s	1990s
No. Issues	103	120	120	120	111
No. Book Reviews	98	143	116	148	242

Movie or TV Reviews
Charles Beaumont was the original movie reviewer for F&SF, doing 10 in the 1950s, as well as one TV review. The TV review, in the December 1959 issue, was for the express purpose for telling the readers about a great new show, The Twilight Zone, for which Beaumont was to eventually write many scripts. In the late 1960s there were 5 movie reviews, 4 by Samuel R. Delany, 1 by Edmund Emshwiller. Baird Searles then began a long run of 163 combined movie & TV reviews, between September 1970 & July 1984. The movie reviews were then taken over by "Harlan Ellison's Watching" columns, a column which first began in the Cosmos SF&F Magazine in September 1977. In the October/November 1991 issue, F&SF's first combined issue, Kathi Maio began reviewing movies, and continues to do so today. Ellison and Maio both write lengthy essay reviews for their movie columns. Since Baird Searles, there has always been a movie review column in F&SF, though it may be published quarterly at times.

Editorials
F&SF's first editorial was by Avram Davidson in the April 1962 issue. He would do 14 during his brief tenure as editor. After the rare editorials by editorial assistant Ted White (2) and editor/publisher Edward L. Ferman (4), the F&SF editorial began to flourish under the editorial helm of Kristine Kathryn Rusch. She wrote 60 editorials during her 70-issue editorship, between July 1991 and May Her editorials were engaging, often asking the readers to respond to them, and perhaps having their responses published as well. She wrote a series of editorials on the publishing industry, titled "A Reader's Guide to Publishing," between July & December 1996, during which she published the opinions of readers and book shop owners. She also wrote of many issues of interest to the reader, such as what the role of an editor should be, writer ethics, and censorship. During his 28 issues as F&SF's editor, at the end of its first 50 years, Gordon Van Gelder has written 8 editorials, including one for its 50th Anniversary Issue, October/November 1999. Hopefully he will write more.

Fiction & Non-Fiction
The following is a chart showing the length of the stories and the number of non-fiction pieces in F&SF through its 50 years, giving the number of issues per decade, as well as average issue size (in pages):

Fiction & Non-Fiction	1949, 1950s	1960s	1970s	1980s	1990s
No. Issues	103	120	120	120	111
Issue Size	128	132	164	164	164*
Vignettes	125	127	44	28	18
Short Stories**	726	583	539	608	567
Novelettes	126	173	222	256	225
Novellas	18	26	36	32	41
Novels	5	7	13	2	1
Articles	25	56	17	5	81
Asimov Essays	14	120	120	120	26
* 244 pages for 8 combined October/November issues; 324 pages for October/November 1999.
** Facetious articles (fa), spoofs (spf), group of related stories (gp), and humorous essays (hues), are included among the short stories.

A few conclusions can be made from this table. Most are obvious. Vignettes which were popular in the first 20 years (65 by Reginald Bretnor alone in his Ferdinand Feghoot series, writing as Grendel Briarton), declined sharply after the 1960s, perhaps because the issue increased by 32 pages in late 1972, favoring the publication of longer pieces. Vignettes and short stories made up the majority of the fiction in the 1950s; the number of short stories per decade stabilized in the 1960s through the 1990s, at roughly about 575 per decade. Novelettes and novellas increased in frequency, also perhaps, as the issue size increased in late 1972. The popularity of the novel was at its most in the 1970s, then quickly died in the 1980s and 1990s.
