Ever wanted to re-read a particular Ray Bradbury story, but didn't know which collection it was in? Allow me to introduce you to a handy feature of Bradburymedia: the Short Story Finder!
The Short Story Finder lists (nearly) every Ray Bradbury story, and tells you where it was originally published, and which Bradbury collections you can find it in.
It also includes the "Eller Reference" for each story. This is a two part number-code which indicates the year of original publication, and the position of publication within that year. For example 46-04 indicates the fourth Btradbury story published in the year 1946. This numbering scheme originated with Jon Eller, Ray's literary biographer, who used it in Ray Bradbury: The Life of Fiction and in the ongoing Collected Stories of Ray Bradbury series of books.
So, without any further ado, I give you:
The Short Story Finder!
