"Immediate implementation of AACR 2 has great potential for alienating users, creating catalog chaos and forcing huge expenses in a time ofchaos, and forcing huge expenses in a time of scarce money.  On those grounds alone, it is clearly prudent to postpone implementation”y p p p pJohn Berry, “’AACR 2’ – a prudent postponement,” Library Journal

1.0 General Rules 

AACR2 1.0F1 specifies that an inaccuracy is to be transcribed followed by “[sic]”, or “i.e.” and a correction in square brackets. Infollowed by  [sic] , or  i.e.  and a correction in square brackets. In RDA [1.7.9], inaccuracies are transcribed as they appear on the source of information. If necessary, a note may be made correcting the inaccuracy and the title as corrected recorded as acorrecting the inaccuracy, and the title as corrected recorded as a variant title if it is considered to be important for access. There is an exception for the title proper of serials and integrating resources to correct the error (RDA 2.3.1.4).

1.1C General material designation 

The General Material Designation has been replaced by RDA Media type (3.2), Carrier type (3.3), and Content type (6.10). 

1.1F Statement of responsibility  

AACR2 1.1F5 limits the number of people or corporate bodies which can be recorded in a single statement of responsibility. RDA does not have this artificial limitation. However, there is an optional omission (2.4.1.5) toartificial limitation. However, there is an optional omission (2.4.1.5) to allow the first person or body to be named and the omission summarized. 

If a single statement of responsibility names more than three persons or g p y pcorporate bodies performing the same function, or with the same degree of responsibility, omit all but the first of each group of such persons or bodies. Indicate the omission by the mark of omission ( … ) and add et al. (or its equivalent in a nonroman script) in square brackets.
