One book I have which has some decent content regarding Anfield and the Kop is as follows.
It's a book about fans more than anything, so doesn't have a dedicated chapter to the Stadium, but has quite a bit of info, and a fair number of large photos, both B/W and colour littered throughout the book.

It being 2004, I'd more than certain it would probably be out of print, but you might pick one up from a secondhand source.
Edit: here you go, this one.http://www.amazon.co.uk/Liverpudlian-Come-Spion-Kop-Football/dp/1906802424/ref=sr_1_1?s=books&ie=UTF8&qid=1350347565&sr=1-1
This one is paperback, with a different dust jacket to mine, and dated 2010, so they must of done a second edition/ reprint/paperback version, although I would expect the content to be identical.
