If your serious about research once you have joined the breed club try to buy at least 10 years Worth of back breed annuals/yearbooks (thats about 3 canine generations), and after you have researched all the dogs behind the pedigrees your working with that far go back further buy buying even more, at least the last 20 years to give you five or 6 generations..
This will allow you to see how individual lines/kennels have developed and how particular dogs have bred on, and what influence they have had for good or otherwise.
It doesn't beat hands on or personal experience of the dogs but it gives you a snapshot of the breeding over time, and a foundation for more research.
I now have yearbooks going back to the 1930's with almost complete set back to the 70's.
