Collection Services Policy and Procedure Manual: RDA new cataloging rules

Short description of RDA changes from AACR2

1.  Terminology has changed a lot for author, titles, volumes into works, expressions, manifestations. 



100 field

    RDA change:Compilers of works by more than one author are again main entry, as they were prior to AACR2. 

    RDA change: Entry under first author, regardless of number.



    RDA change: Treaties are entered under the first country mentioned, regardless of number or alphabetical order, or in the case of a

    treaty between one country and a group of countries, enter under the  one country.



     RDA change: From older records remove "$pO.T." and "$pN.T." from

     between  "Bible" and $p name of the individual books.  For the Old



     and New Testaments, spell out O.T. and N.T.



      RDA change:  Use square brackets only for information not found in

      the item, regardless of source within the item. Leave brackets

      in older records.



    RDA change:  Record all authors given in prime source in 245 /$c.   

    In older records, the title is the main entry in this case, i.e., no 100.)


    RDA change: use first author mentioned as 100. 

    RDA change: "[sic]" or bracketed additional letters no longer used

    after typos.  Create 246 with corrected spellings. 

    RDA change: For compilations, use the RDA option of supplying a title

    in brackets, rather than using the title of the first work as title

    proper.  (This allows us to continue creating only one bibliographic

    record per physical item, a requirement for many of our clients.)




    RDA change:  When/if ILS have made the change, enter media terms in


       336-338 (qv), omitting 245$h.  While 245$h is used, continue to use

       AACR2 terms.



     RDA change: Transcribe all authors, regardless of number.  But, in

     the case of a compilation, transcribe statements of responsibility

     after titles in 505.


     Abandonment of the Rules Of Three removes the need for "[et al.]" or

     "[and others]".    




     RDA change: Transcribe rather than abbreviate, e.g., 250  $a Second  edition.



     SLC will not adopt RDA transcription in full, nor omitting jurisdiction

     if absent.  SLC will transcribe or supply jurisdiction using AACR2

     abbreviations.  Supply missing information in a note does not work

     in brief displays.


     SLC will continue to use ISBD Latin abbreviations rather than English

     phrases, because of our international customer base.



     SLC will Continue to use AACR2 abbreviations, due to different

     spellings in different languages.


      336-338  Cf. 245$h

Before you start reading about RDA keep these in mind:


     Functional Requirements for Bibliographic Records

     This is the theoretical framework under which RDA was constructed. It describes the relationships between and among the different elements in a bibliographic record.

     WEMI = Work, Expression, Manifestation, Item

     MARC is a carrier of data. The tags and subfields were designed so that a machine could manipulate the data. Many people think that MARC isn't a good carrier for newer data about data (metadata). Many catalogers think that MARC doesn't do RDA justice and if we had a better carrier, we'd appreciate RDA more.



     International Standard for Bibliographic Description

     You probably learned about ISBD  in library school. RDA uses ISBD punctuation in most places.



     Resource Description and Access

     These are the new rules for describing things that will replace AACR2

     For summary or explanations of what and why see the JSC brochure

     Also from the Toolkit support site

General Information

In 2013 RDA = Resource Description and Access = new cataloging rules will be implemented by the Library of Congress and the library world.  Here is some information given at the AALL 2012 annual meeting about RDA.


RDA records in OCLC Connexion were shown as well as the new macros and drop-down menus for original catalogers. Also shown were step-by-step instructions on how to view RDA records in the Library of Congress catalog at


 With RDA records being added every day, simply clicking on "KEYWORD SEARCH," selecting "EXPERT" and then typing "k040 rda" allows you to view RDA records in full or MARC format.  Also you can add "and k955 xg?" to your search terms to limit your results to law-related records.

More information


In OCLC you can search for these records using a variety of search strategies that you would normally use but limiting them to dx:rda  

   dx is a new index that searches the 040 $e

You can also limit your search by formats: eg.  dx:rda and mt:ser (for serial RDA records)

or by date dx:rda/2011

or dx:rda/2011/dlc          [searches for LC rda records]
