Library of Congress Classification Overview
CAUTION: some Old Yale class numbers resemble LC class numbers in form but differ from LC in scope, e.g.
| Class number | LC scope | Old Yale scope |
| B50-B96 | Philosophy | History of civilization |
| CE | Technical chronology | United States history |
| E | United States history | Geography |
| P | Languages and literatures | Law |
As a rule of thumb, even when Old Yale call numbers only use capital letters, they may be identified by their use of lower case letters in some of their cutters and the use of numeric book numbers; also, in most cases Yale adds "(LC)" below the call number for classes that might be mistaken for Old Yale. The number of potentially overlapping situations appears to be quite small. However, since the Voyager call number index in the Orbis OPAC interfiles all classifications, catalogers need to be reasonably alert to the differences when shelflisting. (The interfiling is currently under review.)
| LC | Old Yale |
| P71 R6 (LC) | P71 939L |

- Library of Congress Discontinues NACO Literary Author Number Program (July 1, 2018) - All works by or about an individual literary author are generally classified together in the same number or span of numbers in class P, although multiple numbers or spans of numbers may be established for authors who write in more than one language. To allow for a high level of consistency, the classification number assigned to an author may be recorded in the author’s name authority record.
