Building an improved resource discovery experience for users: a cataloger’s experience and perspective
CEAL ConferenceToronto, Canada, March, 2012Jia XuThe University of Iowa
Overview
• To build an improved resource discovery experience for users, an important cataloging procedure is to achieve consistency of bibliographic headings
• The projects/tasks aiming to achieve consistency of bibliographic headings within the records for Chinese videos and filmso Update personal and corporate name headingso Test Aleph functionality on the automatic updating of
bibliographic headingso Examine inconsistency of existing genre/form
headings• What we have achieved and learned
Aleph Authors index search: “Meng, Jinghui”: the results before and after updating the bibliographic heading. “Heading Information” is missing.
Heading Information?
The project to update personal name and corporate name headings
• Technical reasons to update bibliographic name headingso There had been an increasing number of
bibliographic name headings within the existing records that did not match the authorized headings Newly established authorized headings Updated authorized headings Formerly undifferentiated authorized headings
o Aleph functionality has not been robust enough to support the automatic updating of headings within bibliographic records
The project to update personal name and corporate name headings
• Steps toward consistency of bibliographic name headingso Verify the bibliographic heading against the authorized heading
Li, Yu, 1973- ( 李玉 , drt, aus, 红颜 , 苹果 ) o Establish and/or update name authority records
Song, Jia, 1962- ( 宋佳 , act, 淘金王 , 落山风 , 寡妇十日谈 ) Song, Jia, 1980- ( 宋佳 , act, 好奇害死猫 , 闯关东 , 赤壁 ) Yu, Faye, 1971- ( 俞飞鸿 , act, 牵手 , 千年敬祈 ) Chao, Winston ( 赵文瑄 , act, 饮食男女 , 红玫瑰白玫瑰 ) Chu, Chunqiu, 1959- (pen name, 楚春秋 , real name, 徐贵祥 ,
aut, 弹道无痕 , 历史的天空 )o Keep bibliographic headings updated
Updating bibliographic headings requires ongoing efforts and enhanced system functionality
Test Aleph functionality on the automatic updating of bibliographic headings
• OCLC Closed Dates in Authority Records http://www.oclc.org/rss/feeds/authorityrecords/default.htm (Including CJK authority records)
• Special Aleph fields in authority recordso UPD: code: Y or N, determining whether or not to update the
bibliographic records automatically o COR: a see reference for the original authorized heading
• Identified system problemso Does not link the authority record to the bibliographic record(s)
in some caseso Updates the paired bibliographic headings to the authorized
form o Changes the order of subfield 6
???: Missing link between the authority and bibliographic records
???
Aleph updated the bibliographic heading from “Engle, Paul, 1908-” to “Engle, Paul, 1908-1991” successfully.
A test result: if changing UPD code from N to Y in the authority record, Aleph updates the paired fields and moves subfield 6 to the end of the 100 fields.
Examine inconsistency of genre/form headings
• Local policy on the assignment of genre/form terms for foreign films had been changed over the past ten yearso Geographic subdivision for “country of production”
Provide the information in 500 field --> Add the subdivision to five genre/form headings --> Add the subdivision to topical heading “Foreign films” --> No longer subdivide genre/form headings geographically
o “Foreign films” and “Foreign television programs”Assign the headings for foreign films and TV programs --> Do not use the terms (for they are no longer LCGFT terms, but LCSH headings)
o Source thesauriLCSH --> GSAFD and LCSH --> LCSH -->LCGFT
o MARC coding650 --> 655 --> 650 and 655 --> 655
Time period Local policy on genre/form headings for foreign films Relevant fields in bibliographic records: examples

What we have achieved
• Updated 450 personal and corporate name bibliographic headings by matching them with the authorized headings within 1500 records for Chinese videos and films; created and updated 70 personal and corporate name authority records
• Tested how Aleph functions to automatically update name headings (Latin and non-Latin names) in 100s, 600s, 700s, 800s; also, subject headings in 650s
• Examined inconsistency of existing genre/form headings, the first step leading to a potential future project, to fix inconsistency of genre/form headings within existing records for the libraries’ moving image collection
What we have learned
• It is important to look at bibliographic data from user’s perspective• Authority control procedures are the key steps to support user tasks
o The system-generated link between bibliographic and authority records is crucial to control bibliographic headings and to direct users to authorized heading information
o The verification procedure is a key step to match the bibliographic heading against established authorized heading
o Establishing and updating authority records aids catalogers to identify, contextualize, justify the entity; the authority data then aids users to identify, select the entity
• Achieving consistency of bibliographic headings requires ongoing efforts and enhanced system functionality
• Must prepare to transition to implementation of RDA, a standard designed to focus attention on fulfilling user tasks
