Accelerando, by Charles Stross (pub. 2005)
This is a series of interconnected stories. I read at least one of them when it was originally published a few years earlier in Asimov's Science Fiction Magazine. I don't really remember anything about the story, but I remember liking it, so... when this book came out, I thought I'd like to read it. Eventually.

Dangerous Visions (pub. 1967)
An anthology edited by Harlan Ellison, with stories by many great writers.

Dark Matter (anthologies, pub. 2000, 2004)

Impossible Things, by Connie Willis (pub. 1993)
A collection of short stories, which I own but haven't gotten around to reading yet.

The Martian Chronicles, by Ray Bradbury (pub. 1950)
I don't think I've read any of this, but I can't say for sure. At the very least I must have seen some adaptation of it, but I don't really remember about that, either. Anyway, I definitely want to read it. And I should probably read some of his other work. (I have read "Fahrenheit 451," but I don't remember it well, so I should reread it.)

Stories of Your Life and Others, by Ted Chiang (pub. 2002)
I'd also like to read his second collection, "Exhalation: Stories."

Tales from Watership Down, by Richard Adams (pub. 1996)

Virtual Unrealities, by Alfred Bester (pub. 1997)
This is a collection of Bester's short stories, which I have owned for a good number of years now and haven't gotten around to reading yet. But I will.

The Woman Who Thought She Was a Planet and Other Stories, by Vandana Singh (pub. 2009)

Zenna Henderson
At some point in my youth, I read a story called "The Believing Child," which is in one of Henderson's short story collections, "Holding Wonder." I don't recall for sure where I read it, but my best guess would be maybe Read magazine. (Or... maybe somewhere else.) Anyway, someday I'd like to read it again, so I reckon I should get a copy of Holding Wonder. And I suppose if I like a lot of the stories in that collection, I might want to get some of her other works.
