The linked story is part of the online version[0] of a Baen anthology, _The World Turned Upside Down_, being a collection of stories that formed the imaginations of the two editors, Erik Flint[1] and David Drake[2]. The site seems to have been created in 2004, and for some reason is sprinkled with nonstandard characters and primitive formatting, which is a shame.
The list of stories in the contents[3] is indeed wonderful. I instantly recognize and remember "The Menace from Earth", "Black Destroyer", "A Pail of Air", "Who Goes There" (the original from which _The Thing_ and many other productions derived) and others.
