C4LN 2013 - RDA 2
RDA is…
Replacing AACR2 as the content guidelines for bibliographic & authority data to support resource discovery
Based on IFLA’s entity-relationship models “Functional Requirements for Bibliographic Records” and “Functional Requirements for Authority Data”Focused on the use of the data to find,
identify, select, obtain, clarify, understand
C4LN 2013 - RDA 3
RDA is not… An encoding standard A display standard
0.4.2.3 Flexibility: The data should function independently of the format, medium, or system used to store or communicate the data. They should be amenable to use in a variety of environments.
C4LN 2013 - RDA 4
Implications for MARC
New & revised fields
Hybrid records
C4LN 2013 - RDA 5
Implications for Search & Display & Sort & RIS export etc.
New fields and subfields to index & displayPay special attention to the 264 field for
publication, distribution, manufacture, copyright information
New fields to replace the general material designation (GMD)Do you currently use the GMD to identify
resource type?

Some Machine Conversion Examples from the Report
245: Remove the General Material Designation (GMD)
245 subfield c: Remove ellipses and change Latin abbreviation (“… [et al.]” becomes “[and others]”)
300: Spell out abbreviations and change Latin abbreviations to English equivalents
336, 337, & 338: Add these fields, including subfields a, b & 2

C4LN 2013 - RDA 14
Some Issues Should we have multiple pieces of
information in one element? Extent: 300 pages Authorized access point for a work: Hemingway, Ernest,
1899–1961. Sun also rises
We need to use more identifiers Do we need to “dumb-down” library data? RDA Toolkit is subscription based not open Understanding linked data
