Perhaps the best way to scan through the slide rule collection is by way of the images in this chapter. The entries are ordered according to

Model. Some of the dates for the slide rules are accurately known, but for many the dates are simply honest guesses. For a few further details of each rule of the Collection as well as other information regarding manufacturers, see The Slide Rule Collection.
