The Library of Congress Classification (LCC) is a classification system that was first developed in the late nineteenth and early twentieth centuries to organize and arrange the book collections of the Library of Congress. Over the course of the twentieth century, the system was adopted for use by other libraries as well, especially large academic libraries in the United States. It is currently one of the most widely used library classification systems in the world.
The MARC (MAchine-Readable Cataloging) formats are standards for the representation and communication of bibliographic and related information in machine-readable form. Standardized bibliographic data input, utilizing MARC formats, insures the integrity of the online public catalog in storage and retrieval of information. There are several versions of MARC in use around the world, the most predominant being MARC 21, created in 1999 as a result of the harmonization of U.S. and Canadian MARC formats, and UNIMARC, widely used in Europe. The MARC 21 family of standards now includes formats for authority records, holdings records, classification schedules, and community information, in addition to the format for bibliographic records.
WorldCat is a database of cataloging and classification information. Records are machine-readable bibliographic descriptions of items held by OCLC member institutions. The system links each bibliographic record to locations information. Bibliographic Formats and Standards is a guide to machine-readable cataloging records in WorldCat. It provides tagging conventions, input standards and guidelines for entering information into WorldCat.
