Main Street by Sinclair Lewis

She was unexpectedly appointed to the town library-board by Ole Jenson, the new mayor. The other members were Dr. Westlake, Lyman Cass, Julius Flickerbaugh the attorney, Guy Pollock, and Martin Mahoney, former livery-stable keeper and now owner of a garage. She was delighted. She went to the first meeting rather condescendingly, regarding herself as the only one besides Guy who knew anything about books or library methods. She was planning to revolutionize the whole system.

Her condescension was ruined and her humility wholesomely increased when she found the board, in the shabby room on the second floor of the house which had been converted into the library, not discussing the weather and longing to play checkers, but talking about books. She discovered that amiable old Dr. Westlake read everything in verse and "light fiction"; that Lyman Cass, the veal-faced, bristly-bearded owner of the mill, had tramped through Gibbon, Hume, Grote, Prescott, and the other thick historians; that he could repeat pages from them -- and did. When Dr. Westlake whispered to her, "Yes, Lym is a very well-informed man, but he's modest about it," she felt uninformed and immodest, and scolded at herself that she had missed the human potentialities in this vast Gopher Prairie. When Dr. Westlake quoted the Paradiso, Don Quixote, Wilhelm Meister, and the Koran, she reflected that no one she knew, not even her father, had read all four.
