Volume 29 contains 550 pages of Instructions for Pickett slide rules models not included in Pickett Volume 3. This is reference work to preserve slide rules manuals and a continuation of the first Pickett Volume 3.. Many companies are no longer in business after the 1970s. The instruction manuals were never sold separately from the slide rules, and many were lost over time. The project is to provide a composite hard copy book and digital of reprints of instructions from the most popular manufacturer's slide rule models.
