  1. Authority Control: What It Is and Why It Matters Rick J. Block Columbia University

  2. NEW YORK: AN AUTHORITY CONTROL PROBLEM • City • County • Colony • State • State of Mind

  3. WHAT CAN BE FOUND IN BOBCAT • Assignment for Introduction to Bibliographic Control • Illustrates importance of authority control and quality cataloging

  4. HOUSTON, WE HAVE A PROBLEM • Three headings for same person • Pseudonym and real name not linked • Unauthorized heading used

  5. AUTHORITY CONTROL IS: • the process of maintaining consistency in the verbal form used to represent an access point in a catalog • the further process of providing interconnections among names, works, and subjects which display any significant relationship

  6. AUTHORITY CONTROL IS • the process of ensuring that every entry – name, uniform title, series, or subject – that is selected as an access point for the catalog is unique and does not conflict, by being identical, with any other entry that is already in the catalog or may be included at a later date.

  7. Goals of Authority Control • Facilitate the identifying and collocating functions of the catalog • Users can assume that a consistent term or phrase will refer to a particular name, title or subject, and that variations will be brought together under the one form

  8. A=blixen, karen • Blixen, Karen, 1885-1962 • Search also under • Dineson, Isak, 1885-1962

  9. S=cody william f • Cody, William Frederick, 1846-1917 • Search under • Buffalo Bill, 1846-1917

  10. What Needs to Be Controlled? • Subject terms • Personal names • Corporate names • Geographic places • Titles

  11. Problems with Personal Names • Pseudonym or pen name • Initialized first name • Omitted first name • Non-roman alphabets • Married name vs. maiden name • Compound surname • Names with nobility • Changed names

  12. Authority Control • Not so difficult: 66% of all authors write only one book in one edition. But the remaining 34% can be very difficult--changing names, variations, translations, different alphabets, etc.

  13. Lin Yu-tang Ching-chun Hsieh Nelson Chou Jack Kai-tung Huang Nancy Ou-lan Hu Chou Surname first Surname last Chinese first name dropped English first name adopted without dropping Chinese first name Woman’s married name with English first name Patterns of Chinese Names

  14. Married name vs. Maiden Name • Good example: • Elizabeth Taylor

  15. PETER BROWN IN CLIO • 29 headings • 9 cross-references • 18 different people • 73 titles • 3 incorrect (two on order records)

  16. Brown, Peter, 1925- Brown, Peter, 1948- Brown, Peter Hume, 1849-1918 Brown, Robert Lamont Brown, 1935- Book of Kells, Chaucer Medieval manuscripts, Chaucer Medieval church, early Scotland St. Augustine, Roman Church, women in early Christianity The Many Faces of Peter Brown

  17. Authority Control Purposes • Uniformity • Verification • Linkage

  18. Authority Work • Includes the research work and intellectual effort involved in creating and updating authority records • Determines if a relationship exists between names or subject heading terms • Establishes and links the names that could refer to the same person • Establishes relationships between subject heading terms • Includes recording the authority data of preferred form, variants, history, scope, and links to other authority records

  19. Steps of Authority Work • Researching for variants • Choosing one among many • Analyzing parts of the term • Adding, omitting or modifying the term • Handling special language cases • Linking the used and the unused • Document the process

  22. SYNDETIC STRUCTURE • Means “Connective” and is derived from classical Greek • Conceived by Charles Cutter who defined syndetic catalog as “that kind of dictionary catalog which binds its entries together by means of cross-references so as to form a whole.” • Great cocktail party term

  23. How would you search following in catalog? • Heinrich von Kleist • Ephraim Ben Baruch • Jose Martinez Ortiz • Elizabeth Sutherland Martinez • National Archives and Records Administration

  24. Authority Record • Result of authority work • A record which shows a heading in the form established for use in the catalog • Lists cross-references to be made to and from the heading • Cites the sources consulted in establishing the heading

  25. Authority File • Set of authority records • Lists the names, series and subject headings that have been established and used in a catalog and provides links to related subject headings, titles and names

  26. Authority Files • Needed for efficient cataloging and searching in library networks • Reduce effort involved in entering headings • Avoid duplication of work • Improve the quality of catalogs

  27. Four Functions of Authority Files • Authority function: support consistency of headings • Finding function: provide links from variants and other authorized headings • Information function: show usage and scope of headings • Maintenance function: support manual and automatic error detection and correction

  28. Advantages of Authority Control • Collecting, recording and maintaining authoritative forms of headings • Linking variant forms of headings together • Providing consistency and verification upon creating bibliographic records • Automatic verification • Global change and correction • Shared authority files • Linkage between authority files and bibliographic records

  29. Problems with Corporate Names • Name change • Names in different languages • Variant names • Brief form of names • Subordinate and related bodies
