How To Find A Book
The books in this library are arranged on the shelves according to the Library of Congress Classification System, which separates all knowledge into 21 classes as outlined below. Each class is identified by a letter of the alphabet, subclasses by combinations of letters, and subtopics within classes and subclasses by a numerical notation.
The Complete Library of Congress call number for any book may be found by consulting the card catalog. The Librarian will be happy to assist you if you are unable to find the book you want.
