Hello. Newbie here. I came up with a little method for encoding text. Was encouraged to post it here. Anyone wanna give it a shot. Here's the text:

OMIIERSSPTIEESNMHOPSOREODNNEHABOJFTIAVEAKAETNRWSSH AEWSIGTUFRADRFTENOTAURSCHOEOSTR

Hint #1: It's the actual letters of the coded message. No substitutions.
Hint #2: The text was manipulated twice. Not exactly the same way each time, but essentially so, based on a key which can be figured out from the scrambled text.
Hint #3: It's very famous text from a very famous author.

Enjoy.

Edit: I cannot get this to post without the space between the H and A two-thirds of the way through. The space is meaningless.
