Identifying Shimano/Campy components(1 post)

I have numerous campy and shimano components (cassettes, chainrings etc, both 8 and 9 speed and from various years) lying around. I'm not sure whether some of them are dura-ace or ultera, record or chorus. Does anyone know of a site that explains components (other than current year components) in enough detail for me to identify them as either one or the other. Is there always a difference between dura-ace/ultegra and chorus/record (ie. if I had a chainring or single sproket from a particular group/year, would I be able to identify it as such)?
