Oughtred Society Reference Manual
 
 

8-1/2 x 11 inches, 104 pages, paperback, copyright 2005 by the Oughtred Society.  There are better sources on principles, history and how to use slide rules but they are not all together in one book.  Includes information on cleaning and repair that you cannot find anywhere else.  There is no better collection of color photographs of slide rules published anywhere.  Well over 100 photographs including pictures of 99 (by my count) different slide rules ranging from common to rare antiques.

Brand new $35.
