As part of the conversion of the LC NAF, the 7XX fields on AACR2 records that have RDA forms (7XX _ 4) need to be removed and/or evaluated. There have been about 14,700 records identified that can be dealt with programmatically. These changes will be done in the LC database and distributed through the regular LC distributions. The project to do this will start January 7, 2013. They will change about 4000 records per day until done. This means there will be a few weekly update files from LC that will be significanly larger than usual. We want to make sure everyone is aware of these upcoming changes. If you have questions or concerns about how this will affect you and what your options are, please contact your project manager. Since it looks like the announcement was only sent to the PCC list, I'm including it in it's entirety below: "The PCC Acceptable Headings Implementation Task Group (PCCAHITG) designed plan for changes to the LC/NACO Authority File in the context of the adoption of RDA, including the phased changes to the authority file. As you are aware, the Phase 1 changes were completed in August 2012, and Phase 2 changes are scheduled for 2013. The Task Group has also identified a small subset of records that have 7XX fields with RDA forms that need to be dealt with before the Phase 2 changes begins. After reviewing options for manually changing the records, the Task Group developed plans to adjust most of the records automatically by program and issued that plan for comment on September 27th, 2012 (http://files.library.northwestern.edu/public/pccahitg/RDA_conversion.Rd a7xxFields.Automated.doc). In moving forward with this plan, a program was developed by Gary Strawn at Northwestern University. Over 17,000 records were identified, although some of these records will be reserved for manual treatment. After extensive testing by LC and Northwestern University, the number of records to be programmatically changed will be about 14,700. Categories of records that won't be adjusted programmaticaly include pre-AACR2 records (008/10= a,b, or d), records that contain a 7XX with an element that is a candidate for a change in Phase 2 regardless of the field in which it appears (e.g., abbreviations such as fl., ca., arr., O.T., Dept. ), records containing "Jr." in the 700 field, and others where the 7XX and 1XX were significantly different so as to warrant manual review. Like the Phase 1 changes, these records will be adjusted in the LC database and distributed to the NACO nodes and other CDS customers. The changes will begin January 7, 2013, with about 4,000 records adjusted per day until it is completed. These records will be issued in addition to the regular distribution of LC/NACO transactions. Once this small project related to RDA 7XX fields is completed, testing of the logic for the Phase 2 changes must begin-- we are now recruiting volunteers to help with this testing. If you are interested in helping, please send a note to the PCCAHITG member Karen Anderson kanderson@bslw.com by January 4, 2013. The timing of the Phase 2 changes will be dependent on successful testing, so any help is greatly appreciated." As you can see, I'm on the PCCAHITG, so if you have any questions about the RDA/NAF conversion, feel free to contact me.
