MAJOR RDA CHANGES FROM AACR2 BY MARC FIELD                 3 June 2009

These changes will not be adopted unless and until they begin appearing
in derived national cataloguing agency records.

LDR/18 new code for RDA?

100 
`
     RDA change: Entry under first author, regardless of number.  But enter 
     only under a author who shares responsibility for the whole work, not 
     the first work in a collection.

     RDA change:  Compiler continues to be main entry for compilations
     such as bibliographies, bibliographies, and indexes, not the works of
     others; but consider compiler main entry for collections with a supplied
     collective title.

110
     

     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.

130

     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 themselves, spell out O.T. and N.T.

     

2XX
     RDA change:  Use square brackets only for information not found in 
     the item, regardless of source within the item. Leave brackets
     in older records.
          
245 

     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 has flip flopped on removing alternate title from title proper,
     currently leaving it in as does AACR2.  SLC will follow client
     preference in not considering alternate title to be part of title
    proper:
