Lucky girl! I treasure the few old math and science books I have from my Dad.

These are from my grandfather, who was a math professor; he got his PhD during the Great Depression. Among them are several texts by Allendoerfer and Oakley (I presume he was considering them for courses he was teaching), Chrystal's two-volume textbook of Algebra, and several texts on Calculus from the late 1800s and early 1900s.

I can understand!
