Back in my repair shop days I had a Chiltons for every year dating back to the stone age. The guy I bought the shop from had been in business a long time & I just kept adding to the library each year I was there. When I sold the shop they went with the contents all but the years I needed for the vehicles we had at the time. They didn't sem that important then.
