TRANSCRIPT
RDA Test at LC: June 2010 -- Module 1 2
RDA is successor to AACR2
but is not AACR3 -- RDA is different from AACR2
RDA Test at LC: June 2010 -- Module 1 3
RDA based on IFLA’s international models and principles
Functional Requirements for Bibliographic Records (FRBR; 1998)
Functional Requirements for Authority Data (FRAD; 2009)
Statement of International Cataloguing Principles (ICP; 2009)
RDA Test at LC: June 2010 -- Module 1 4
Addresses user tasks
FRBR: Find Identify Select Obtain
FRAD: Find Identify Contextualize Justify
• ICP’s highest principle = “convenience of the user”
RDA Test at LC: June 2010 -- Module 1 5
Is a content standard
Not a display standard (as was AACR2) Does have appendix D for ISBD and
appendix E for AACR2 style for access points
LC will continue using ISBD punctuation and AACR2 style for access points (also see LCPS 1.7)
Not an encoding standard LC will use MARC 21
RDA Test at LC: June 2010 -- Module 1 6
For wider scope of resources
Response to what’s being acquired in libraries More elements for non-printed text resources More elements for non-text resources More elements for unpublished resources
Compatible with specialist manuals (DACS, CCO, DCRM(B) etc.)
RDA Test at LC: June 2010 -- Module 1 7
Includes authority data instructions
Based on attributes and relationships in FRAD
Authorized/variant access points and elements will for now be documented in authority records
RDA Test at LC: June 2010 -- Module 1 8
Has controlled vocabularies
Only a few closed: content, media, and carrier types; mode of issuance; etc. If term missing, tell PSD
Most are open: cataloger can supply term if needed term not in list Tell PSD which term used
Some vocabularies being registered on the Web
Training document #1 has list
RDA Test at LC: June 2010 -- Module 1 9
What’s changing?
Changes in technology Impact on descriptive/access data
book catalogs card catalogs OPACs next generation
Move from classes of materials to elements and values (more controlled vocabularies)
Move from individual library to international audience
RDA Test at LC: June 2010 -- Module 1 10
Internet
Catalogs are no longer in isolation Global access to data
Virtual International Authority File (www.viaf.org)
Integrate bibliographic data with wider Internet environment Share data beyond institutions
RDA Test at LC: June 2010 -- Module 1 11
RDA developed for the future
Full advantage of RDA-based data: When authority and bibliographic data reside
in separate “packages” and records assembled when needed
When access points (if needed) can be assembled “on the fly”
When data for works and expressions can be reused for multiple manifestations
RDA Test at LC: June 2010 -- Module 1 12
RDA appendices for transition
Appendix D mappings: ISBD to RDA - few changes from current
practice MARC 21 bibliographic format to RDA
Appendix E: Presentation and punctuation of access
points - few changes from current practice MARC 21 authority format mapping to RDA
RDA Test at LC: June 2010 -- Module 1 14
RDA Structure
General introduction Identifying elements (entities and their
attributes) Ch. 1-7: work, expression, manifestation, item Ch. 8-16: person, family, corporate body, place
Relationships: ch. 17-22, 24-32 Appendices Glossary
RDA Test at LC: June 2010 -- Module 1 15
RDA structure Not by class of materials: no separate
chapters for books, printed music, etc. Overarching principles applicable to all
Basic goals: identify and relate (from FRBR/FRAD user tasks and ICP)
Chapters: separate elements for goals Assemble those elements when need
authorized access points (instructions at end of chapters 6, 9-11)
RDA Test at LC: June 2010 -- Module 1 16
Not to be read linearly Using an online tool:
“Jumping in” via keyword searches Going directly to elements from Table of
Contents (ToC) pane Following links Seeing some duplication of content (needed
for context) Separate RDA Toolkit training/demos Can use Training documents #3 and #4
to go to specific instructions
RDA Test at LC: June 2010 -- Module 1 17
What is where in RDA?
Supplemental Training documents:
#2 = Where is it in RDA? (general information)
#3 = RDA core elements (listing of elements by
chapter for a general overview of RDA)
#4 = LC RDA core elements for the RDA Test
#6 = Bibliographic record: MARC to RDA
#7 = Authority record: MARC to RDA
RDA Test at LC: June 2010 -- Module 1 18
Terminology
FRBR and FRAD “attributes” are “elements” in RDA
FRBR and FRAD Group 1 entities: Work Expression Manifestation Item
RDA Test at LC: June 2010 -- Module 1 19
Group 1 entities
“Book”
– Door prop(item)
– Publication at bookstore -- any copy(manifestation)
RDA Test at LC: June 2010 -- Module 1 20
Group 1 entities
“Book”
– Who translated?(expression)
– Who wrote?
(work)
RDA Test at LC: June 2010 -- Module 1 21
AACR2 to RDA vocabulary
heading author, composer, etc.
main entry
uniform title
authorized access pointcreator
preferred title + authorized access point for creator if appropriate
(1) preferred title (+ other information to differentiate);
(2) conventional collective title
RDA Test at LC: June 2010 -- Module 1 22
AACR2 to RDA vocabulary
see reference
see also reference
physical description
chief source
variant access point
authorized access point for related entity
carrier description

GMD media type +
carrier type +content type
RDA Test at LC: June 2010 -- Module 1 24
Examples of addressing user tasks
Variant title “if considered to be important for identification or access”
Length of the film “if considered important for identification or selection”
Other persons associated with the work “if considered important for access”
Cataloger’s note “to justify the … form of the access point”
RDA Test at LC: June 2010 -- Module 1 26
Core elements
Based on attributes mandatory for a national level record in FRBR and FRAD
Core elements (RDA 0.6): Some: always if applicable and available Others: depends upon situation = Core if … Agency can add others
LC’s core elements: Training document #4
RDA Test at LC: June 2010 -- Module 1 27
“Core-ness” identified at element in RDA Toolkit
If always a core element (if applicable and available), label “CORE ELEMENT” appears below element name
If use as a core element depends upon the situation, the label “CORE ELEMENT” is followed by an explanation of the situation
If additional element selected by LC as core, an LCPS will say “CORE ELEMENT FOR LC” with or without an explanation
RDA Test at LC: June 2010 -- Module 1 28
Core elements’ reminder (RDA 0.6)
Include all the core elements that are applicable and readily ascertainable
Don’t do research just to give a core element unless RDA instruction or LCPS says to do so
RDA Test at LC: June 2010 -- Module 1 29
Other choices in RDA
Alternatives and options
“or” instructions
“agency preparing …” instructions
LC’s decisions in tables posted on PSD site and in LCPSs available on PSD site and in Toolkit
RDA Test at LC: June 2010 -- Module 1 30
Choices: alternatives
Instructions saying to do something different from what the previous instructions said, e.g.,
Giving a general note about numerous minor changes in title proper of a serial
Using the label on a direct access electronic resource as source for title proper instead of viewing the resource
RDA Test at LC: June 2010 -- Module 1 31
Choices: optional omissions
Instructions saying to do less than what the previous instructions said, e.g.,
Omitting corporate hierarchy in the publisher’s name
Omitting words in a long title proper
RDA Test at LC: June 2010 -- Module 1 32
Choices: optional additions
Instructions saying to do more than what the previous instructions said, e.g.,
Adding birth/death dates even if that information isn’t needed to differentiate
Adding fuller form of name even if that information isn’t needed to differentiate
RDA Test at LC: June 2010 -- Module 1 33
Choices: “or” instructions
Not labeled as alternatives but do offer different approaches – agency policy decision An example: when giving the extent of a resource
consisting entirely of unnumbered pages, give the exact number, an estimated number with “approximately”, or “1 volume (unpaged)”
Not all instructions with “or” wording are choices: some apply only to specific situations
