AN INTRODUCTION TO UNDERSTANDING LIBRARY CALL NUMBERS . Each material in the library has its own unique call number. It appears in the library’s online catalog. Understanding the Call Numbers and the Classification System will make it easier for you to retrieve Library materials. The call number is also attached to the spine of the book. It is like an address that tells you where the library material is located. It also provides the information such as the subject, First letter of the author’s last name and the year of publication. In the Bertha Smith Library the call numbers are assigned according to the Library of Congress Classification System. It is an alphanumeric system consisting of both letters and numbers. In this Classification System materials are broken down into twenty-one general subject areas. Each Subject area is represented by a letter. A - General Works B - Philosophy, Psychology, Religion C - Auxiliary Sciences of History D - History: General and outside the Americas E - History: United States F - History: United States Local and America G - Geography H - Social Sciences J - Political Science K - Law X (non-LC) - Non Common Law L - Education M - Music N - Fine Arts P - Language and Literature Q - Science R - Medicine S - Agriculture T - Technology U - Military Science V - Naval Science Z - Library Science These 21 subject areas are further divided into subcategories. For an example, see the subcategories under Philosophy, psychology and religion Sub-categories in B: Philosophy, psychology and religion B - History and Systems of Philosophy BC - Logic BD - Speculative Philosophy BF - Psychology BH - Aesthetics BJ - Ethics BL - Religions, Mythology, Rationalism BM - Judaism BP - Islam, Bahaism, Theosophy BQ - Buddhism BR - Christianity (General) BS - The Bible BT - Doctrinal Theology BV - Practical Theology BX - Denominations and Sects The sub-categories are further divided into several subdivision of subjects. These subdivisions are represented by numbers.

E.g.: B BT 121 966.2 .K56 .G7 1970 1986 First Line: The first line of call numbers describes the general subject area. In the example below, the letters “ BT” represent Doctrinal Theology.
