To find books (and other materials) go to the Library homepage and under Quick Links select Library Catalog. Request items online and they will be delivered within 4 hours (on business days) to Book Check Out on the 1st floor of the Library. Book Check Out is open 8a-9p M-Th, 8a-6p Fri, and 10a-6p Sat.
NOTE: It is best to search by "keywords" rather than "subject" unless you know the specific Library of Congress subject heading.
