To Jenkins' Spoiler-Laden Guide to Isaac Asimov Introduction Though perhaps best known throughout the world for his science fiction, Isaac Asimov was also regarded as one of the great explainers of science.
His essays exemplified his skill at making complex subjects understandable, and were written in an unformal style, liberally sprinkled with personal anecdotes that endeared him to a legion of faithful readers.
It was all a labor of love; in particular Asimov often remarked that of all his writing, his essays for The Magazine of Fantasy and Science Fiction were his favorite, despite the fact that he received the lowest word-rate payment for them.
From November to Februaryan essay of his appeared in the magazine every month, without fail. With the advent of Isaac Asimov's Science Fiction Magazine inhe began a series of editorials that appeared at the beginning of each issue.
In addition he wrote essays and introductions for literally hundreds of magazines, newspapers, books, and trade publications. All together he wrote over essays. With such a huge collection of essays, it can pose a problem for the reader who remembers a piece that Asimov wrote, but can't recall the source.
Those who haven't read a great many essays may want to know if Asimov ever wrote an essay on a particular subject. And then there are the Asimov completists who want to read everything that Asimov ever wrote, but lose sleep at night worrying that they might have missed something.
Where do they turn? To that end, we have compiled a list of every known essay by Asimov, together with a brief description of its subject, and listed the source in which the essay originally appeared, as well as any collections of Asimov's in which it appeared.
Please note that the emphasis is on known, since there are undoubtedly some we have missed. We have included every essay that has appeared in Asimov's collections, as well as a good number of those that have never been collected. Also included are introductions Asimov wrote for other books, though in this department we probably have missed quite a few.
Notes on the listings There are some essays that do not appear in any collection and are not readily available, so that the authors haven't read them yet. For those essays the subject field is left blank. That list is ordered alphabetically according to the title of the essay, and includes a designation of the collection in which each essay appears as well as a very brief subject description for each essay.
We have used those descriptions, but have added to them in some places, as well as added our own descriptions for essays published since his list appeared.
