--- Begin Forwarded Message --- Date: Wed, 22 Mar 2000 09:08:06 -0500 From: "Caplan,Ellen" <[log in to unmask]> Subject: OCLC MARC Bib Update & TB236 Sender: "Caplan,Ellen" <[log in to unmask]> This message is being cross-posted to several electronic discussion lists. Please excuse the duplication. At the end of April 2000, OCLC will begin making changes to its implementation of the MARC 21 bibliographic format. Most of the changes from Updates nos. 1-3 of _USMARC Format for Bibliographic Data_ and from changes announced in _MARC 21 Format for Bibliographic Data_ will be implemented. Because there are a number of changes being made, OCLC will implement the changes in this MARC Bibliographic Update project in phases. Technical Bulletin 236 gives the details of all the changes for this MARC Update. It is available on OCLC's Web site at http://www.oclc.org/oclc/tb/tb236/index.htm in both PDF and HTML versions. In addition, OCLC will send print copies to OCLC libraries beginning the week of March 20th. The phased implementation begins in late April. We are planning for a first phase installation date of April 23rd. This includes most of the MARC format changes outlined in Technical Bulletin 236, code list changes, and workform/record display and 006 prompt changes. We anticipate a second phase being installed on May 7th. This includes the changes for Encoding Levels '3' and '4'. We do not have dates for other phases yet. We will notify OCLC libraries if there is any change to our planned installation dates. See Technical Bulletin 236 for complete details. If you have any questions concerning the MARC Bibliographic Update, please contact me.
