Key Takeaways
This chapter discusses sources of cataloging records, introduces the reader to record structures, and provides a brief overview of different encoding systems used for cataloging and metadata records.
Cooperation & sharing
Cooperation and resource description data sharing have been introduced in the field of library cataloging in North America in the early 1900s. Library cataloging initially took the form of copy cataloging and continues today via networks, such as OCLC and the Library of Congress, or by making records available as open linked data. MARC records can also be harvested or downloaded from OCLC WorldCat (membership), the Library of Congress via Z39.50 services, and linked data records from any library open linked data services, using an Application Programming Interface (API).
Library traditions & the semantic web
Recording description data using encoding systems is necessary for machine processing and sharing of the data. Library-specific encoding systems such as MARC require databases and retrieval systems designed specifically for libraries. Encoding systems using XML- and RDF-based schemas can be used by systems designed for the universal information environment and the semantic web. The decisions of which encoding schema is used can affect the interoperability, sharing of data between institutions, systems, and domains, and data re-use.
