About the Pettee System
The Pettee System was developed by Julia Pettee (1872–1967), who was the chief cataloguer in the library of the Union Theological Seminary from 1909 to 1939. The Pettee system was developed specifically for organising theological resources, as Julia Pettee considered the Dewey system unworkable for a specialised collection. This is because the wide range of specialties within the religion class, classified according to the Dewey Decimal System, result in numbers having to be extended to several digits beyond the decimal point, generating numbers too long to fit across the spine labels on books.
While Pettee is no longer being developed as a classification system, it is still widely used by theological libraries worldwide. Within Australia, some libraries have elected to migrate to other systems such as the Library of Congress, but there are still a number of libraries that use the Pettee system. These include: St Mark's Theological Centre (ACT), Gilbert Wright Library at Morling College (NSW), Presbyterian Theological Centre Library (NSW), Dalton McCaughey Library of The Uniting Church (VIC), W. Searle Library Melbourne School of Theology (VIC), Leon Morris Library Ridley College (VIC), and Camden Theological Library (NSW).
Dewey Decimal Classification System
The Dewey Classification System is a secondary system used to organise the Christian Resources Collection, currently housed in the periodicals room.
