10 Library of Congress Classification System (LC)  LC is used primarily in academic libraries.  Like DDC, materials on the same subject are shelved together.  Broad subject groups are identified by the letter or letters found at the beginning of the call numbers; for example:  A represents general works  B represents Philosophy, Psychology, and Religion

11 Superintendent of Documents Classification System (SuDoc)  Used to arrange publications of agencies of the United States government.  This hierarchical system is not subject based. Call numbers represent the government agencies that publish the materials.  The initial letter or letters signify the department or agency that issued the document.
