Does anyone know of a public exclusion words list?

Basicly I'm looking for a list of words such as (a,an,and,of,what,etc...) that I can use to remove words from a standard english sentence and subsequently develop a list of keywords.

I expect that most big search engines have such a list but it seems unlikely that they would be willing to share it and I don't have the resources or time to peruse a dictionary to create a list of my own.
