  1. Machine Readable Cataloging (MARC) 21 Michelle Anderson Lindsay Berry Dorothy Hirsch LI 804

  2. MARC 21 • What MARC is • How MARC was developed • How MARC is used • The future of MARC • Our evaluation of MARC

  3. What is MARC 21? • Stands for MAchine Readable Cataloging • Catalog record includes four things: • Description of the item • Main entry and added entries • Subject headings • Classification or call number • An example of a MARC record:

  4. What does all the coding mean? Let’s take a closer look.

  5. More on MARC • Library of Congress developed the LC MARC format when computer use began • LC MARC system used brief numbers, letters, and symbols to mark different types of information • The LC MARC system evolved into MARC 21

  6. Who is responsible for maintaining MARC 21? • Bibliographic format and documentation is maintained by the Library of Congress • Two groups review and revise MARC 21 content: • MARC Advisory Committee • The Machine-readable Bibliographic Information (MARBI) Committee • Committee of the ALA • Made up of three representatives from technical services, automation services, and reference services

  7. History of MARC 21 • Need for standardized cataloging system • Developed by libraries to get full use out of computers • Made shared cataloging a reality • Made library automation affordable • Comprehensive and flexible record • Two main design components: • Structure-form the information takes • Standard for machine-readable records

  8. History of MARC 21 • Pre-MARC computer systems (early to mid 1960s) • Could only be used by trained library personnel • Could only be used by the library that created the system • Limited use • Circulation • Overdue Notices • Fixed length • About 120 characters • Either too much space or not enough space

  9. History of MARC 21 • Research and Development, MARC I and MARC II • Library of Congress chosen to facilitate research • Research began at LofC in 1965 • Two main focuses: • Development of a machine readable format for library records • Potential use of an automated system

  10. History of MARC 21 • MARC I • Small group of libraries using computers was used as a test group • Became evident that shared records would be a great advantage of an automated system • Searching could be done using non-traditional words of phrases • Gathering of statistics could improve storage and circulation

  11. History of MARC 21 • MARC II • MARC I expanded in 1967 into MARC II • Communication format standard • Magnet tape • Transmission of magnetic tape by US mail • Flexible formatting • System developed into USMARC in the 1980s • Combined with CAN/MARC (Canadian MARC) in 1997 to become MARC 21

  12. Benefits of the MARC 21 system • Prevents duplication of work • Allows libraries to share authority information • Enables libraries to access authority data that is predictable and reliable • Cost effective • Quality enhancing • Prevents librarians from ‘reinventing the wheel’ • Allows all persons who distribute and use authority data to communicate with each other

  13. Uses of MARC 21 • MARC 21 transmits data (specifically bibliographic data) from one system to another • Reduces the work load of librarians by eliminating the need to catalog information that has already been added to the system • Standard form used in machine readable information

  14. Who is Using MARC 21 • The Library of Congress uses MARC 21 • Current LofC classification schedules are produced from records in MARC 21 classification format • Around fifty systems are available to collect, organize, and manage MARC 21 records

  15. MARC 21 Records Systems • Follett Software Company-serves more than 100,000 schools and universities in the U.S. and 165 countries worldwide • Library.Solution-serves thousands of libraries worldwide, includes circulation and self checkout functions • Polaris- serves over 1000 libraries worldwide, has a multilingual edition that includes 115 languages • Koha- free/open source, a community of collaborating libraries worldwide

  16. Future of MARC 21 • There is some competition with other cataloging systems: • RDA • AACR2 • These systems are thought by some to be more in line with ideas of web 2.0 and the semantic web • There is strong support in the library world to adapt and improve the MARC 21 system, rather than switch systems completely
