The tools of our trade: AACR2/RDA and MARC - Presentation Transcript
UKOLN is supported by: The Tools of our Trade: AACR2/RDA and MARC Guest lecture at London Metropolitan University 13 th March 2009 Ann Chapman Community and Outreach Team
What are our Tools?
AACR/RDA = content standard for resource description and access
MARC = communication and exchange format providing a structure for encoding the content of bibliographic and authority data
Related to:
ISBD = rules that organise the display of a bibliographic description of an item in a catalogue
FRBR = a entity-relational model of the data required to find, identify, select and obtain resources
ISBDs
International Standard Bibliographic Descriptions
Developed 1969 onwards by IFLA
Defined seven areas of description and their order
Section 8 : Ch. 24, 25, 26, 27, 28 Recording relationships between works, expressions, manifestations and items
Section 9 : Ch. 29, 30, 31, 32 Recording relationships between persons, families and corporate bodies
Section 10 : Ch. 33, 34, 35, 36, 37 Recording relationships between concepts, objects, events and places
What will RDA look like? - 5

Using RDA
Analyse the resource being described
What is the content type?
Held in what carrier form?
To what other resources is it related?
To which persons, families or corporate bodies is it related?
To what concepts, events and places is it related?
One rule for all …
Mostly:
Rules apply to all content types
Rules apply to all media types
With
Examples of application to specific content and media
Occasionally:
Rules apply to specific materials or contents (e.g. treaties, religious texts, music)
Words, words, words …
Can look opaque or ‘going round in circles’
Trying to avoid reference to specific content and carriers
Hope to improve wording over time
‘ Use as the preferred source of information a source forming part of the resource itself that is appropriate to (a) the type of description and (b) the presentation format of the resource .’
Means preferred source of information may vary according to
Comprehensive or analytical description
Multiple pieces, early print, moving images, or ‘all other materials’
RDA – What will it be?
Initially an online resource
Complete text
Pricing, subscription, etc. – still not decided
Potentially:
Concise text
Tailored texts (law, music, serials, etc.)
Training resource
Incorporated into LMS cataloguing modules
Loose-leaf print version(s)
RDA and beyond
RDA aims to be:
Independent of communication formats
UNIMARC, MARC, MARCXML, MODS/MADS
DC, EAD, ISBD, VRA, MPEG7
Compatible / better aligned with other similar standards
Archives: ISAD(G)
Museums: Cataloging Cultural Objects
RDA and MARC
Mapping RDA and MARC 21
Report issued in Nov. 2006; various proposals subsequently go through MARBI process
How will RDA impact on MARC 21?
Some new fields / subfields are being defined
How will MARC 21 impact on RDA?
Data provisions in MARC 21 not covered in current draft of RDA
MARC – 1960s
Library of Congress project
Database of catalogue records
Production of catalogue cards
US & UK versions
Reflected differing cataloguing practices
Developed in parallel but not identical ways
MARC – 1970s
Variant formats developed
Based on either US or UK formats (AUSMARC, DANMARC, KORMARC, etc.)
USMARC developed 8 material formats (Books, Serials, Maps, etc.)
UNIMARC developed in 1977 by IFLA
Intended as exchange format
Used as the Bib format in some countries (e.g. France)
MARC – Recent changes
Expansion of USMARC to a family of formats
Bibliographic, Holdings, Authority, Classification, Community Information
Integration of USMARC bibliographic format
Previous 8 formats integrated
Widespread adoption of MARC 21
Some countries simply adopt USMARC
1997 – USMARC & CANMARC become MARC 21
2003/4 – MARC 21 enhanced by UK proposals; British Library adopts MARC 21
2006/7 – MARC 21 enhanced by German proposals: this will enable libraries to move from MAB to MARC 21
MARC Structure
Leader
0xx – control numbers, coded data
1xx – primary access point
2xx – description, GMD, edition, publication
3xx – physical description
4xx – series
5xx – notes
6xx – subject access points
7xx – additional access points
8xx – series added entries
9xx – local fields
Maintaining MARC 21
Twice yearly MARBI meetings
Discussion papers
Proposals

MARC and XML
MARC has alpha-numeric 3-digit tags
100.1 Personal Name
245 $a Title $b Subtitle
XML has element labels
<namePersonIndirectOrder>
<title> <titleSubtitle> <titleCoverTitle>
Looking into the crystal ball
FRBR
Potential influence on cataloguing systems
Authority records, uniform titles, work records
OPACs
Multiple interfaces for different audiences
Enhance for accessibility - supports all users
Links (actual resources, restrictions, supporting or associated resources)
RDA
Potential use outside the library domain

Guest lecture at London Metropolitan University on more
Guest lecture at London Metropolitan University on 13th March 2009. The lecture covered the history behind RDA, the international collaborative process by which it is being developed, an overview of the text and a look at the RDA approach to cataloguing; this was followed by an overview of the history and development process for the MARC format. less
