With the decision of the National Libraries to adopt RDA sometime after Jan. 2013, we are anticipating more interest how legacy AACR2 records and RDA records should be handled.\u00a0 We are already seeing an increase in the number of RDA records being produced and there are several institutions cataloging fully with RDA.<\/p>\n

<\/p>\n

Although we are currently able to process both AACR2 and RDA records, we know that having both types of records in the same database can be problematic for some library systems.\u00a0 We are in the process of creating a crosswalk that would allow us to move AACR2 records to an RDA format or move RDA records to an AACR2 format.<\/p>\n

There are several issues with trying to move from the one format to the other.\u00a0 Since RDA is based more on direct transcription of what is on the resource, it will not always be possible to make a completely accurate crossover from AACR2 to RDA without the item in hand. One example of this would be the change from using abbreviations in AACR2 that would be spelled out in RDA, unless the abbreviation is used on the item. So when making the change from AACR2 to RDA, there would be no way to be absolutely accurate in all cases without that item in hand.\u00a0 The most commonly seen instance of this is with \u2018dept.\u2019 to \u2018department\u2019, and \u2018ed.\u2019 to \u2018edition\u2019.<\/p>\n

Another example is the change from using a GMD in the 245 $h in AACR2 records to using more \u00a0specific terms for content type, media type, and carrier type in RDA which are put in fields 336-338.\u00a0 It would not always be possible to take the general designation used in AACR2 and know what the correct terms should be for the more specific fields in RDA without the item in hand.<\/p>\n

These are just a couple of examples.\u00a0 We would like solicit feedback from those of you who might be interested in doing a crosswalk.\u00a0 What issues do you see?\u00a0 How would you like things handled?\u00a0 What margins of error are acceptable?\u00a0 What would you need for your specific systems?<\/p>\n

Feel free to email me, Karen Anderson, at kanderson@bslw.com<\/a> or if you are coming to ALA, come join us at the MARS Breakfast Saturday morning.\u00a0 We would love to discuss things with you personally.<\/p>\n","protected":false},"excerpt":{"rendered":"
