  1. Authority and MARCA Match Made in Heaven Donna Schroeder OHIONET October 21, 2004

  2. Today’s Agenda • Why have Authority Control? • What does it mean to you • MARC • Why is it important?

  3. Why Have Authority Control? • Ensures consistency • One heading / one person • Ensures uniqueness • Julie Andrews is different from Julie Andrews, bassoonist • Serves a record-keeping function • Keep catalogers from redoing work

  4. Why Have Authority Control? • Items can go missing. Lost to the user • Even Amazon tries a form of authority control to get customer to the item

  5. Why Do Authority Work • Administrators may • Consider it expensive • Cost exceeds benefits • Slows down the cataloging of wanted materials

  6. Unseen Cost • Burden is placed upon the user to know or guess all possible forms • Frustration limits success • Library may acquire additional copies of works already owned by the library or covered by the library’s collection

  7. For Example • Gabriel Garcia Marquez • File under Marquez or Garcia • If filed two ways….

  8. Robinson Crusoe • Original title Life and Strange Surprising Adventures of Robinson Crusoe of York • Other versions have other titles • Imagine trying to find all versions • One uniform title brings all together

  9. Time Consuming • Yes. It takes time at first • If set up carefully can be easy to maintain • Authority service • Individual

  10. Time Consuming • Time spent in the beginning saves your users time • More likely they will get what they need • User satisfaction

  11. Authority File • Most heavily used is the Library of Congress Authority File by libraries and by outside sources. • Comprised of two divisions • Subjects • Names

  12. Library of Congress • Depends on AACR2 for formation of names • Subject headings are based on the Subject Cataloging Manual

  13. Access to Authority File • Free online access http://authorities.loc.gov/cgi-bin/Pwebrecon.cgi?DB=local&PAGE=First • Through a service such as RLIN or Connexion

  14. Makes Life Easier • Using an already developed Authority File makes life easier • Not in Authority File? • AACR2 guidelines • What language, which country, which is the entry element, etc….

  15. Local Authority Records • Create your own • Caveat. • It is very time consuming and requires a lot of reference work • Example:

  16. Made up authority record

  17. See Also ReferencesName • Jean Plaidy, Victoria Holt, Philippa Carr • By linking all identities customers can find all items by one search

  18. This is an authority record

  19. Bibliographic IdentitiesName • Lewis Carroll wrote his fantasy books under Carroll • Charles Dodgson wrote his mathematics books under Dodgson • Same person

  20. Wrote works under two names Clearly split

  21. In conclusion • Authority work is a benefit to the user • Who is your user • Students • Teachers • Staff • Public (for shared catalogs)

  22. Half the Cataloging Battle • Authority is half the battle • The other half is MARC

  23. MARC • Machine Readable Coding • Why MARC?

  24. Computers • Imagine trying to get the information from a card into a computer. • How could you tell a computer to display this line as a title and this as a date?

  25. Coding • The computer can’t read punctuation but it can read code attached to the punctuation and that is what MARC is.

  26. Local System • SIRSI can take the coding and translate it into something a student can read • Library staff decide what information should be included

  27. Library System Programmer • Programmer takes the request and writes the program for the library’s OPAC • That is why OPACs can vary from library to library

  28. Coding • Brief numbers, letters, and symbols within the cataloging record mark different types of information

  29. How • Punctuation is determined in the record by the International Standard Bibliographic Description (ISBD) (included in AACR2)

  30. : and / in Title • : is followed by ‡b • / is followed by ‡c • Placement of : and / determines coding, NOT the other way around

  31. Codes • 245 = Title/Statement of responsibility • ‡b = other title information • ‡c = statement of responsibility • 14 = Main entry and number of letters to ignore at the beginning

  32. Title - 2nd Indicator • Tells search system to ignore initial articles • A (2) • An (3) • The (4) • Le (3) • La (3) • L’ (2)

  33. Example • 245 14$aThe DNA story : $b a documentary history of gene cloning / $c James D. Watson, John Tooze.

  34. Text display

  35. Same record MARC display

  36. Web2

  37. In Conclusion • MARC is simply coding • Easy to use • Allows for an online catalog

  38. Today We Looked At • Authority Control • It is important to help our users find items in our collections • MARC • Is coding used to compose a record and make it available via a computer
