Video Orientation to the University of Pennsylvania Library's LJS 164, 3 volumes, mostly disbound, of sample problems copied by members of the McCormick family of Georges Township, Fayette County, Pennsylvania, from arithmetic textbooks published in the first half of the 19th century. The first volume was copied in 1822 and possibly 1823 by James McCormick from Joseph Stockton's Western calculator, or a new and compendious system of practical arithmetic, published in many editions, the first in 1818. Notes and accounts at the back of the volume are dated 1825 and 1826. The second volume was copied circa 1839-1845 by William Hampton McCormick, earlier sections also from the Western calculator and later sections with more complex mathematics from Jeremiah Day's Introduction to algebra, published in many editions, the first in 1814. The third volume is an unsigned fragment in a different hand dated 1823, copied from Zachariah Jess's American tutor's assistant, improved, or a compendious system of decimal, practical arithmetic, published in many editions, the first in 1799. Stockton's textbook covers very similar material to Jess's, focusing on arithmetic to be used in the contexts of finance, retail, and building trades.
