UNIX History for term paper

I am gonna write my term paper on UNIX and was wondering if anyboady had and good places where to get references. I found one really good book. But I need at least 5 really good sources of info. Can be video, magazines, book, or site. But it needs to be a really good site cause my teacher checks websties.

Heres some links for ya. If I remember correctly Unix was originally developed in Bell Laboratories.

If you need more info just google for it. You will find a ton of info.

This is a very, very good site on Unix history including an excellent map http://www.levenez.com/unix/

Thank you very much this will a lot.

Does anyone have any info on the people who made unix?

In the link i posted there are pictures of 6 or so guys with beards and a link to each of there homepages , the first 3 or 4 are all unix/c creators and the last two are the creators of GNU and Linux.

Thanks again lumpyporridge.
