Authority Records in a Networked Environment

This comprehensive guide explores the critical processes of contributing, deriving, and merging authority records in a cooperative national file within a networked environment. It outlines best practices for achieving optimal search recall and precision, ensuring data compatibility with established standards, and addressing international cooperation in authority data. By following the proposed guidelines and optimizing the integration of various data sources, libraries can enhance the coherence and efficiency of their authority records, promoting effective international collaboration.

  1. Authority Records in a Networked Environment

  2. Network Scenarios • Contributing records to a cooperative national file • Deriving records from external sources • Merging records into a composite multinational/multilingual file

  3. 1. Contributing to a cooperative file Cooperative File 1. Search 2. Identify 3. Integrate Library A Library B Library C

  4. 2. Deriving from external files Source A Source B Source C 1. Search 2. Identify 3. Integrate Library File

  5. 3. Merging into composite file Composite File 1. Search 2. Identify 3. Integrate Library A Library B Library C

  6. Search  Identify  Integrate • Search • optimize recall • Identify • optimize precision • Integrate • compatibility with file standards • coherency of reference structures

  7. Search : Optimize Recall(1) Search authorized and variant headings HEADINGS SEARCHED HEADINGS IN FILE  1 Debure, Guillaume Bure, Guillaume de 2 < Bure, Guillaume de

  8. Search : Optimize Recall(2) Exclude additions to heading from search term HEADINGS SEARCHED HEADINGS IN FILE 1 Smith, Russell E. (Russell Eugene) Smith, Russell E.  2 < Smith, Russell Eugene

  9. Search : Optimize Recall(3) Search on original script / transliterated forms HEADINGS SEARCHED HEADINGS IN FILE  1 Ts`ao, Hsüeh-ch`in Cao, Xuequin 2 Cao, Xuequin

  10. Identify : Optimize Precision(1) Compare additions to headings HEADINGS SEARCHED HEADINGS RETRIEVED 1 Brown, George, Rev. Brown, George, Captain  2 Brown, George, Rev.

  11. Identify : Optimize Precision(2) Compare supplementary data in notes, etc. HEADINGS SEARCHED HEADINGS RETRIEVED 1 Du Jardin, Thomas Du Jardin, Thomas Nationality: French Nationality: Belgian  2 Du Jardin, Thomas Nationality: French

  12. Identify : Optimize Precision(3) Compare reference structures HEADINGS SEARCHED HEADINGS RETRIEVED 1 1 Stewart, J.I.M. Stewart, J.I.M. 2 << Innes, Michael < Innes, Michael  2 Innes, Michael <<Stewart, J.I.M.

  13. Integrate : Compatibility(1) Conformity with rules, etc. HEADINGS SEARCHED HEADINGS RETRIEVED 1 Charles IV, Roi de France Charles IV, King of France Rules: AFNOR Rules: AACR  2 Charles IV, Roi de France Rules: RCAA

  14. Integrate : Compatibility(2) Established order of preference among sources HEADINGS SEARCHED HEADINGS RETRIEVED 1 Beeton, Mrs. Beeton, Mrs. Nationality: British Nationality: British Source: British Library Source: British Library 2 Beeton, Mrs. (Isabella Mary) Nationality: British Source: Library of Congress 

  15. Integrate : Coherency(1) Elimination of conflicts in reference structures HEADINGS SEARCHED HEADINGS RETRIEVED 1 1 Stewart, J.I.M. Stewart, J.I.M. 2 << Innes, Michael < Innes, Michael  EDITED RECORDS 2 Innes, Michael 1 Stewart, J.I.M. <<Stewart, J.I.M. << Innes, Michael 2 Innes, Michael <<Stewart, J.I.M.

  16. Facilitating international sharing • IFLA Working Group on an International Authority System • Guidelines for Authority and Reference Entries • Guidelines for Authority Records and References • UNIMARC Authorities • International Cooperation in the Field of Authority Data • Minimal Level Record for Internationally Shared Resource Authority Records • Working Group on Functional Requirements and Numbering of Authority Records (FRANAR)

  17. Objectives • Specify data requirements • Define data structures • Develop an international numbering scheme

  18. Issues • Understanding the function of the data • data supporting identification • data embodied in the heading (e.g., name, dates) • data recorded in cataloguer’s notes (e.g., field of activity) • data recorded in coded form (e.g., nationality, gender) • data supporting integration • data identifying the source and status of the record • data identifying the language of the record or data element • data identifying scripts, transliteration schemes, character sets, etc.

  19. Issues • Clarifying data definitions • differentiating categories of data elements • e.g., distinguishing between “name” and “addition” Leighton, Frederick Leighton, Baron Beeton, Mrs. • clarifying underlying concepts • e.g., nationality (place of birth? citizenship? place of residence?) Du Jardin, Thomas [birthplace: France; residence: France] Du Jardin, Thomas [birthplace: France; residence: Belgium]

  20. Issues • Potential for automatic editing • complexities in language of cataloguing AFNOR: Charles IV, Roi de France [‡8frefre] AACR: Charles IV, King of France [‡8engfre] AFNOR: Abrantès, Laure Junot, duchesse d’ [‡8frefre] AACR: Abrantès, Laure Junot, duchesse d’ [‡8engfre] AFNOR: Valmer, capitaine [‡8frefre] AACR: Valmer, capitaine [‡8engfre]

  21. 1 Stewart, J.I.M. << Innes, Michael 2 Innes, Michael <<Stewart, J.I.M. 3 Stewart, J.I.M. < Innes, Michael Issues • Accommodating differences in cataloguing rules and practice • recognition of discrete entities (e.g., author who uses one or more pseudonyms)

  22. Issues • Administration of an international numbering scheme • responsibility for assigning an ISAN • jurisdictional responsibility • first-in • procedures for ensuring validity of assignment • international register • national/regional registers • linking authority and bibliographic files • adding ISANs to heading fields in bibliographic records
