It reminded me again of the comparison between this and the switch from AACR1 to AACR2. AACR2 was published in 1978, but not implemented until 1981, after having been postponed at least once from the original projected date of implementation. It was necessary to continue to teach AACR1 for students even after 1981 because of the practice of considering some headings to be "AACR2 compatible" -- that is, the AACR1 heading was accepted and continued to be used in new records in instances where the entity in question was not well known (and a few other cases). In addition, thousands of records created according to AACR1 and earlier rules continued to be in the majority in catalogs for many years (at least through the 1980s); so students who were going to be catalogers needed to have some understanding of the older rules. I believe this will also be the case when RDA is implemented. --Arlene ************************************************** Arlene G.
