• Call numbers have a minimum of three lines, the last being the publication date.
• To find a book’s call number, search IvyCat, the Library catalog, for the book’s record.
• Call numbers are assigned by subject area, so browsing through nearby books may lead you to more books on your topic.
• Call number labels on books are read from left to right, starting with the top line.
