Where can I find the original novelette version of "Flowers for Algernon"?

I need the original one not the novel he wrote later. I need an online source that has it.

Where can I find the original novelette version of "Flowers for Algernon"?
Truly-free.org has it listed but it doesn't say whether or not it's the full length novel or the novelette. Here's the link for the site so you can check it out for yourself; when you get there click on the author's name (Daniel Keyes): http://www.truly-free.org/#fF





Good luck to you! :-)
