OCLC PRISM Union List Update (Myrtle Myers) Ann Ercelawn 21 Jun 1994 20:09 UTC
Date: Tue, 21 Jun 1994 15:57:20 -0400 (EDT) From: Myrtle Myers <Myrtle_Myers@OCLC.ORG> Sender: "SEREDIT: SERIALST Editors" <SEREDIT@UVMVM.BITNET> CEO document contents: OCLC PRISM Union List Update I have become aware in the past few weeks of a number of misconceptions about what is going to occur when OCLC reimplements the Union List Subsystem into the PRISM environment. Following is a high-level overview of some of the changes that will be occurring: Standards With PRISM Union Listing OCLC will be implementing the serial holdings standard Z39.44-1986 at the summary level (Level 3). The standard gives two options for displaying chronology and enumeration. OCLC will be using Option B which is not a change (Example: v.1-v.2 1993-1994), with the exception of the use of captions it is exactly as it is currently displayed in the current UL System. There are, however, three other major changes that libraries need to be aware of, (1) captions are now required if they appear on the piece, (2) gaps in holdings are recorded only if a library owns none of the volume, and (3) the code for permanent retention has changed from a blank to an '8'. During the database conversion involved with the PRISM Union List Installation OCLC will automatically add the retention code of '8' to all Local Data Records that currently have a blank in the subfield 'f'. There are other minor changes involved with the standard, libraries who do not already own the standard should purchase a copy and begin to familiarize themselves with the changes involved. A chapter on the standard will be included in the new OCLC Union List User Guide. OCLC does expect libraries to begin inputting their serial Local Data Records according to the Z39.44-1986 standard once PRISM Union Listing has been installed, however, OCLC does not expect libraries to go back and retrospectively convert the Local Data Records that are currently on the system. Libraries will continue to use the Z39.57-1989 standard for inputting their non-serial LDRs. Local Data Records No holdings data will be lost during the installation of the PRISM Union List System. There will be some minor changes to the Local Data Record: (1) Date recorded (SIHD & SCHD subfield d) will now be an eight digit date (YYYYMMDD), (2) To conform with the Z39.44-1986 serials standard we have added two new data elements to the fixed field, Physical Form (Phys form:) and Holdings Type (Hld type:), (3) we have added an LDR number (this number is not searchable), (4) Regularity will no longer be transferred from the bibliographic record to the Local Data Record, and (5) non-Serial Local Data Records will now display the ISBN instead of the ISSN. Serials Union List Offline Products Serial Union List Offline Products will not change. The only difference libraries can expect to see is the retention code of '8' where they previously saw a blank (on the Tape products this code would be in position 12 of field 008). There are no other changes, the dates will still be 4 digits and the new data elements in the fixed field will not be in the offline products. Enhancements 1. Union List displays in both the Union List and ILL Systems will reflect ILL supplier status (upper/lower case). 2. Libraries who are authorized to do so can now catalog their items in the Cataloging System, change systems to Union List and build their union list information without losing their search. 3. Union List libraries will be able to take advantage of the PRISM searching and editing capabilities. For additional information on PRISM Union List and on what you can do to prepare for it watch you OCLC logon greetings, local Network publications and/or contact you local OCLC-affiliated Network office or you can contact me directly.
