Introduction

I have been writing short stories for fifty-one years and I haven't yet quit. In addition to the hundreds of short stories I have published, there are at least a dozen in press waiting to be published, and two stories written and not yet submitted. So I have by no means retired.

There is, however, no way one can publish short stories for this length of time without understanding that the time left to him is limited. In the words of the song: "Forevermore is shorter than before."

It is time, therefore, for Doubleday to pull the strings together and get all my fiction-short stories and novels, too-into a definitive form and in uniform bindings, both in hard and soft covers.

It may sound conceited of me to say so (I am frequently accused of being conceited), but my fiction generally has been popular from the start and has continued to be well received through the years. To locate any one story, however, that you no longer have and wish you did, or to find one you have heard about but have missed is no easy task. My stories appeared originally in any one of many magazines, the original issues of which are all but unobtainable. They then appeared in any of a multiplicity of anthologies and collections, copies of which are almost as unobtainable.

It is Doubleday's intention to make this multivolume collection definitive and uniform in the hope that the science fiction public, the mystery public (for my many mysteries will also be collected), and libraries as well will seize upon them ravenously and clear their book shelves to make room for Isaac Asimav: The Complete Stories.
