Customers whose last AUP run was prior to the first quarter of 2013 will be seeing RDA-related heading changes for the first time. For details, see the 1st Quarter 2013 AUP Processing Notes.
The abbreviation for South Australia as a qualifier was recently changed from S. Aust. to S.A. LC has slowly begun to update records (see Adelaide (S.A.) as an example). Of the several hundred headings that include (S. Aust.), only eight have been converted so far. LTI will update usage as the changes come through from LC.
