On the internet, an essay: The Norman Yoke: Symbol or Reality by Michael Wood. It is on the BBC history site, but easiest way to find it is simply to google the title.
Please note not one single book gives you a complete picture, but if you know little about this period of history and would like to know more then the two books by Marc Morris are an excellent starting point - both with extensive bibliographies.
