3. Henry Vezin is extensively referenced in Reed, Brunton, and Richards but original source material is difficult to obtain. Possibly the best reference to Vezin's sampling philosophy is found in A W Warwick Notes on Sampling The Industrial Publishing and Printing Company Denver (1903). This small book has been extensively republished in ebook format.
