When Library of Congress (LC) decided to fully implement RDA cataloging, LC, with the support of the PCC, determined that the LC\/NACO Name Authority File (NAF) should also be fully RDA in order to support RDA cataloging.<\/p>\n
March 31, 2013<\/strong> has been set by LC \u00a0as Day One for RDA Implementation<\/strong>. After this date, all cataloging and authority at LC will be done in RDA.\u00a0 See the following link for the whole announcement and the training plan:<\/p>\n http:\/\/www.loc.gov\/catdir\/cpso\/news_rda_implementation_date.html<\/a><\/p>\n PCC also decided that a Day One for the NAF was necessary and it has been set as the same day\u2013 March 31, 2013. After this date, all records added to the NAF must be coded RDA<\/strong>, and all access points on bibliographic records coded \u201cpcc\u201d must be RDA.\u00a0 There is no Day One set for bibliographic records<\/strong>.\u00a0 See the full announcement for more details on PCC\u2019s decision:<\/p>\n PCC Day One for RDA Authority Records (docx)<\/a><\/p>\n PCC\u2019s original plan to migrate the NAF called for a 3-phased approach to the conversion to RDA:<\/p>\n Phase 1<\/strong>\u2014Mark those records that can\u2019t be automatically changed to RDA with a 667 note to the effect that they must be reviewed and\/or updated to RDA before they can be used.<\/p>\n Phase 2<\/strong>\u2014Make computer programmable changes to headings to update them to RDA standards.<\/strong><\/p>\n Phase 3<\/strong>\u2014Code the rest of the records that can be used just as they are as RDA.<\/p>\n This approach would have meant the eventual re-issue of almost all of the approximately 8.3 million<\/strong> name authority records, with some 641,000 records being issued more than once.\u00a0 For more details about this initial plan, see the following link for the original Task Force\u2019s final report:<\/p>\n Report of the Task Group on AACR2 & RDA Acceptable Headings (docx)<\/a><\/p>\n Concern over the size of the proposed updates led the PCC Acceptable Headings Implementation Task Group to devise three alternate implementation scenarios<\/strong> for consideration by the library community and PCC. \u00a0On May 4, 2012 the PCC Policy Committee announced its acceptance of Scenario 3 for the migration of the NAF to RDA. This scenario calls for a 2-phased approach and the eventual re-issue of approximately 641,000<\/strong> authority records, which is a considerable reduction from almost 8.3 million.<\/p>\n I\u2019ll give a brief overview here of what is planned for each phase of the migration but please visit the Task Group\u2019s website for detailed information:<\/p>\n http:\/\/files.library.northwestern.edu\/public\/pccahitg\/<\/a><\/p>\n Documents on this website give details for every change to be made. \u00a0Please also see the Phase Implementation of RDA (doc)<\/a> on the Task Group\u2019s webpage for a more comprehensive overview. \u00a0You can also find information on the original plan and the other alternate scenarios that were proposed.<\/p>\n Comments on all documents are being taken until June 1, 2012<\/strong>, so leave a comment on the Task Group\u2019s Facebook<\/a> page or send them to any member of the Task Group listed here: Charge to the PCC Acceptable Headings Implementation Task Group (doc)<\/a> (scroll down to view member list).\u00a0 As I am also on that list, feel free to send any comments or questions directly to Karen Anderson<\/a> and I\u2019ll be happy to forward them on to the Group. \u00a0PCC members may also post comments to:<\/p>\n https:\/\/www.surveymonkey.com\/s\/G3KCMNT<\/a><\/p>\n All records updated in any way during the two phases will be distributed as part of the regular Library of Congress weekly updates.\u00a0 The rate of distribution of the updated records has generated the most concern, so please be sure to add your voice<\/strong> to that ongoing discussion if you have a strong opinion on the distribution phases.<\/p>\n Here is a brief overview of how the conversion of the NAF to RDA will happen:<\/strong><\/p>\n PHASE 1<\/strong>: Add an identifying 667 field to authority records whose 1XX fields can\u2019t be used as–<\/strong>is under RDA and are not susceptible to any automated change. Records to be labeled fall into three categories:<\/p>\n 1)\u00a0\u00a0\u00a0\u00a0\u00a0 AACR2 records whose 1XX field contains elements at variance with RDA practice. (AACR2 Headings Excluded from Conversion (doc)<\/a> contains a description of these elements)<\/p>\n 2)\u00a0\u00a0\u00a0\u00a0\u00a0 Pre-AACR2 records.<\/p>\n 3)\u00a0\u00a0\u00a0\u00a0\u00a0 AACR2 compatible heading records.<\/p>\n Note<\/strong>: while the exact wording of the 667 field has not yet been determined, one prevalent suggestion is along the lines of: \u201cTHIS 1XX FIELD CANNOT BE USED UNDER RDA UNTIL THIS RECORD HAS BEEN REVIEWED AND UPDATED\u201d<\/p>\n Phase 1 means the issuing of an estimated 313,000<\/strong> records and should take 3-4 weeks<\/strong> to complete. Testing of Phase 1 is currently being done at the Library of Congress and the hope is to complete the phase by early summer 2012<\/strong>.<\/p>\n PHASE 2<\/strong>: Modify authority records whose 1XX, 4XX, and 5XX fields are subject to automated manipulation. The automated changes are listed below with links to the documents giving details for each one.<\/p>\n The following headings changes will be performed on access fields (1XX, 4XX, 5XX):<\/p>\n
