Greetings, Michael : Here at Southern Illinois University, Carbondale, it's a very similar situation to Penn State as to the mixture of record quality between older AACR2 (and others) and the current RDA. If I come across an older record when I'm adding to or downloading new content from OCLC, I'll update (or overlay) the new record to conform to the latest RDA standards. But it's certainly the quality of the overall record that is paramount, be it AACR2 or RDA. An older record, as long as it accurately displays the information from the map, should work well. I hope this helps! :) William J.

Michael, At Penn State, at least for our maps records (haven't a clue about other format teams in my department) we always upgrade an AACR2 (or earlier standard) record to RDA standard, largely because we are PCC members in NACO and BIBCO programs that require that level of work. There's always a mixture of record quality on OCLC though, so in many cases accepting a high-quality or even better-quality AACR2 record without enhancement should be fine for institutions should they choose that path. I'll be interested to see what other responses to your question are, but in my opinion it is the quality of the record itself (accuracy, completeness, use of authorized access point headings) that is of more importance than choice between AACR2 and RDA.

Either way, why? We're reviewing our map cataloging practices and wondering what others do (and why). Thanks for any input you've got. mf -- Michael Fry Collections Manager | Map Library Manager National Geographic Society Library 202.807.3139 [log in to unmask]<mailto:[log in to unmask]> [Image removed by sender.
