RDA: What it is --

A Content Standard

RDA provides instructions on recording the content of records.
  • It does not provide instruction on how a given library system (e.g.) should display the bibliographic information (although there is information about displaying RDA content).
  • Nor does it provide instruction on encoding the information. RDA is schema-neutral. You can use it with any schema, including MARC, or Dublin Core.

More International

RDA is less Anglo-centric than AACR2.  It focuses on user needs, as stressed in the International Cataloguing Principles.

In addition, the agency preparing the description can make choices regarding the:
  • language of additions to access points
  • language of supplied data
  • script and transliteration
  • calendar
  • numeric system

Wider Scope of Resources

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  • unpublished resources

But RDA defers appropriately to the specialist manuals of collaborative communities in situations where more detailed description is wanted than the general view provided by RDA (e.g., music, sound recordings, moving images, electronic resources, cartographic materials).

Authority Data

RDA includes instructions on authority data, based on attributes and relationships in the FRAD model. There were no AACR2 rules for authority data and authority records. RDA doesn’t indicate how authority data should be encoded; but for now, that information will continue to be documented by most libraries in authority records.

Controlled Vocabularies

RDA has many controlled vocabularies. Only a few of the vocabularies are closed (e.g., content type; media type; carrier type; mode of issuance). 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).

Libraries may decide to include some of these controlled vocabulary terms in templates; ILS vendors could provide them in drop-down lists.  And so on. 

The RDA vocabularies are now registered on the Web. The existence of those machine-readable controlled vocabularies will allow more machine manipulation of data than is now possible, including the mapping of RDA to other metadata schemes.

Thanks all for your love, support and suggestions. Please post your feedback and comments on RDA Blog Guest Book. Select remarks will be posted on RDA Blog Testimonials page.



RDA Blog : RDA Blog is a blog on Resource Description and Access (RDA), a new library cataloging standard that provides instructions and guidelines on formulating data for resource description and discovery, organized based on the Functional Requirements for Bibliographic Records (FRBR), intended for use by libraries and other cultural organizations replacing Anglo-American Cataloging Rules (AACR2). This blog lists description and links to resources on Resource Description & Access (RDA). It is an attempt to bring together at one place all the useful and important information, rules, references, news, and links on Resource Description and AccessFRBRFRADFRSADMARC standardsAACR2BIBFRAME, and other items related to current developments and trends in library cataloging practice.

RDA Blog History: RDA Blog was created by Salman Haider, a Cataloging & Metadata Librarian Blogger & Online Social Media Expert from India. RDA Blog embarked on its journey to provide useful information to Resource Description and Access (RDA) in August 2011. It received good response from librarians, catalogers, and library professionals from all around the world. It is interesting to note that the first hundred thousand pageviews to RDA Blog came in 3 years, but it took just 8 months to reach another hundred thousand pageviews. At present it is viewed at a rate of fifteen to twenty thousand times per month. RDA Blog is widely followed in social media.

RDAExpress : a service to convert any library catalog to RDA

A clean database is the key to providing library users the best possible searching experience and catalogers have dedicated years of service in cultivating and maintaining their databases to this end. The new RDA standard has great benefits, providing enriched content and priming libraries for a Linked Data environment, but it also has an impact on workflow, budgets and patron experience. RDA holds the promise for libraries to restructure its data to provide a better searching experience for users and ultimately link outside the library to be more competitive in today’s digital world.  Most integrated library systems are compliant with RDA, in that they can handle a mixed database of AACR2 and RDA records, but is that really helpful to your users? A mixed database results in a mixed display, with your newer records providing more specific information than your legacy records, disrupting search and discovery.

RDAExpress ( promises to help address this disruption and take the headache out of retrospective conversion of your database to RDA - an undertaking that is nearly impossible for catalogers to do while still keeping up with new titles. It is an RDA Conversion service to upgrade your existing records without worrying what kind of ILS you currently have. 
"Our service is going to unleash greater discoverability in library catalogs" says Heather Powers, eBiblioFile Product Owner. “Library records will have more and better relationships and descriptions. The catalog will be ready for FRBR. And the best part is that RDAExpress does all the work to make this possible now.”

Additional information on use of $b in fields 336-338

Library of Congress has begun supplying $b codes for the equivalent terms in $a of fields 336 (Content type), 337 (Media type), and 338 (Carrier type). This is the most efficient manner to start populating a subfield that LC initially chose not to apply. This will allow LC records to conform more to records produced outside of LC (e.g., OCLC generally adds the codes in $b in new records). It will be supplied automatically if cataloger are using the macro or the RDA templates in Voyager—staff are not expected to manually add $b to fields in existing records that lack the subfield.

Appendix I : New Relationship Designators

There are three new relationship designators Appendix I

organizer [I.2.2]
cartographer (expression) [I.3.1]
minute taker [I.3.1]

[Source : RDA Toolkit]

Comments by Aaron Kuperman, Law Librarian, Library of Congress : This list is flexible. It is expected that new terms will be constantly added. Consider it as being similar to how LCSH grows, rather than the former system under LCRI under changes were few and far between.

Editor of Compilation vs Compiler


RDA Relationship Designators : Editor of Compilation vs Compiler 

The editor of a compilation, as defined in I.3.1, is not a creator of a work and thus has to be treated as a 700, not a 100.

On the other hand, a compiler (for example of a dictionary, a directory, a bibliography, etc.) can be considered a creator (see I.2.1) and thus can be treated as a 100.

Expert remarks by Aaron KupermanLaw Librarian, Library of Congress A good rule of thumb is that a compilation needs to consist of works that can (and should) be listed in the contents note.

According to RDA Toolkit: I.2.1 Relationship Designators for Creators: 

Compiler : A person, family, or corporate body responsible for creating a new work (e.g., a bibliography, a directory) by selecting, arranging, aggregating, and editing data, information, etc. For a compiler as a contributor, see editor at I.3.1.

According to RDA Toolkit: I.3.1 Relationship Designators for Contributors: 
EditorA person, family, or corporate body contributing to an expression of a work by revising or clarifying the content, or by selecting and putting together works, or parts of works, by one or more creators. Contributions may include adding an introduction, notes, or other critical matter, or preparing the expression of a work for production, publication, or distribution. For major revisions, adaptations, etc., that substantially change the nature and content of the original work, resulting in a new work, see author at I.2.1.

I.2 - Relationship Designators for Persons, Families, and Corporate Bodies Associated with a Work
I.3 - Relationship Designators for Persons, Families, and Corporate Bodies Associated with an Expression


Relationship Designators for Contributors
The relationship designator for “editor of compilation” has been deleted, and the concept incorporated into a revised relationship designator for “editor.”

Conventional Collective title / Uniform title : Questions and Answers

Answer : The relevant RDA rule for this case is - Complete Works in a Single Form which prescribes to Record one of the conventional collective titles as the preferred title for a compilation of works that consists of, or purports to be, the complete works of a person, family, or corporate body, in one particular form such as: Correspondence, Novels, Speeches, Lyrics, etc ...

Comment : Remember that is not a closed list so you can choose whatever term is appropriate if it’s not already listed there. As this a compilation of Pracanda’s interviews, the 240 is correct. Under RDA, the decision to create a conventional collective title (formerly “uniform title”) based on whether the title proper is adequate or not (as we used to under AACR2, .cf LCRI 25.10) no longer applies.



I.2 - Relationship Designators for Persons, Families, and Corporate Bodies Associated with a Work
