The Kingdom of Matthias by Preus Library uses the Library of Congress (LC) system to shelve books, journals, DVDs, CDs, and other items. LC call numbers group library materials into subject categories, or classes; each class is identified by a letter. Classes are broken down into subclasses by adding more letters; subtopics within are identified by numbers.
Because library materials are organized by subject, if you’re headed to the stacks to find a book, take a minute to browse the shelves around the book, too. You’ll likely find more books on the same or similar topics!
