Library of Congress Classification is a system developed by the Library of Congress in Washington D.C. as a way of organizing very large numbers of books into subject areas by a series of letters and numbers.  PHSC, and most academic libraries use this system.  Every item cataloged is given a special series of letters followed by numbers that place the item on the shelf with others in the same subject area.  LC is arranged from A through Z, and each letter stands for a broad subject.

     At public or school libraries, a different system is used. This system is called the Dewey Decimal system and the call number usaully begins with a number using a decimal and ends with the abbreviation of the author's last name.

The Library of Congress is the largest library in the world, containing millions of books, manuscripts, and other important material. To search the Library of Congress Catalog go to the following link
