The document provides instructions on changes between AACR2 and RDA standards for cataloging. Some key changes include:
1. RDA uses less cataloging jargon and focuses on user needs rather than catalog card displays.
2. Elements like headings, uniform titles, and physical descriptions have been renamed or expanded to better reflect the resources being described.
3. Controlled vocabularies are more open and machine-readable in RDA to allow for more flexibility and automation.
4. Punctuation, abbreviations, and transcription rules are standardized differently between the two standards. Options that were choices in AACR2 are now part of the main instructions in RDA.

RDA Terminology
2. AACR2 RDA Notes
heading authorized access point “heading” reflects outmoded ‘catalog-card-speak’
author, composer, artist, etc. creator
main entry
preferred title and, if appropriate, the authorized
access point for the creator
“main entry” reflects outmoded ‘catalog-card-speak’,
related to cards in a file cabinet
uniform title
Two RDA counterparts:
1. the preferred title and any differentiating
information;
2. a conventional collective title such as “Works”
see reference variant access point
see also reference authorized access point for related entity
physical description carrier description
GMD
three elements:
1. content type
2. media type
3. carrier type
GMD was an inconsistent presentation of different
categories of information
chief source preferred sources
This is not only a change in terminology; ‘sources’ have
been expanded from a single source to multiple sources
3. It provides instructions on recording the content
of records
It does not provide instruction on how a given
library system should display the bibliographic
information
Nor does it provide instruction on encoding the
information.
RDA is schema-neutral.
4. RDA is less Anglo-centric than AACR2
It focuses on user needs
In addition, the library policy can make discretion
regarding the:
language of additions to access points
language of supplied data script and transliteration
calendar
numeric system
5. RDA also covers the wider scope of resources
being acquired in libraries today.
It provides for more elements for:
non-printed text resources
non-text resources
unpublished resources
6. Has many controlled vocabularies
Only a few of the vocabularies are closed (e.g.,
content type; media type; carrier type)
Most of the vocabularies are open; you can
either supply your own term as needed, or
suggest a term be added to the vocabulary (or
do both).
7. Libraries may decide to include some of these
controlled vocabulary terms in templates
ILS vendors could provide them in drop-down
lists.
The RDA vocabularies are now registered on
the Web. The existence of those machine-
readable controlled vocabularies will allow
more machine manipulation

13. The instructions that were in AACR2 formed
the basis of the text for RDA, so you will find
that MANY of them haven’t changed much.
They may have been reworded to make them
easier to understand, but they’re still there
14. •Still includes options and alternatives,
like AACR2 does, and many of these are
the same, though there’s more now.
• Some AACR2 options have become part
of the main instructions of RDA.
15. 1. Title and statement of responsibility
2. Edition
3. Material or type of publication specification
4. Publication
5. Physical description
6. Series
7. Notes
8. Standard number
16. •Still uses MARC records that we are used to
•There are some changes to MARC
18. RULE OF THREE – NO MORE
RDA allows the cataloguer to list all of the author’s listed

19. No abbreviations
Edition terms to be transcribed as they are on
the resource
If abbreviated on the resource then they are
abbreviated in the catalogue data
If spelled out on the resource, they will not be
abbreviated as they would have been in AACR2
