Othmer Library After Hours
It’s National Library Week!
This year, we’re celebrating America’s Semiquincentennial with the theme “A Blast Through the Past: 250 Years of American Science.”
Explore the scientists, ideas, and technologies that have shaped our world from 1776 to today through our unique collections.
See rare and modern treasures, support the library by adopting a collection item, enjoy our annual book-themed cake, and take home a souvenir!
Admission is free; registration is required.
