Harold L. Manley Collection, 1911-1949

The Harold L. Manley Collection consists of lecture notes and problem sets from mathematics and engineering classes that Manley took at Oregon State College in 1939-1940 as well as several mathematics and engineering textbooks. Of particular interest are lecture notes from a numerical calculus class taught by W.E. Milne and a 1949 numerical calculus textbook by Milne.

In addition to the numerical calculus lecture notes, the collection includes problems in differential equations and statically indeterminate structures.  The textbooks include Numerical Calculus: Approximations, Interpolation, Finite Differences, Numerical Integration, and Curve Fitting by W.E. Milne (1949); Elementary Differential Equations by Lyman M. Kells (1935); Strain Energy Methods of Stress Analysis by A.J. Sutton Pippard (1928); Theory of Elasticity by S. Timoshenko (1934); and Elements of the Differential and Integral Calculus by W.A. Granville (1911).
