Library of Congress Classification
Link
The Library of Congress Classification (LCC) is a system of library classification developed by the Library of Congress. It is used by most research and academic libraries in the U.S. and several other countries, for example, Australia and Taiwan, R.O.C. It is not to be confused with the Library of Congress Subject Headings or Library of Congress Control Number. Most public libraries and small academic libraries continue to use the Dewey Decimal Classification (DDC).

Dewey Decimal Classification
The Dewey Decimal Classification (DDC) system is the world’s most widely used library classification system. The 23rd edition of the DDC enhances the efficiency and accuracy of your classification work in ways no previous editions have done.
You can use the DDC in several convenient formats. The four-volume print edition includes thousands of updates added to the system over the past seven years. The electronic version, WebDewey, enhances the print updates with online delivery that is updated continuously. And the Abridged Edition 14, also available in print and online, is a simplified version perfect for smaller collections. Whether you choose the print or electronic format (or both), DDC 23 makes it easier than ever to organize your library collections.
The DDC evolves continually to keep up with recorded knowledge. You can find news about DDC developments in several ways, including a semiannual DDC newsletter, DDC
conferences and workshops, OCLC Newsletter articles and case studies.
