Rules for Merging MELVYL Records. Technical Report No. 6. Revised.
The University of California Catalog and Periodicals databases each have over 20 separately contributing libraries, and records for the same work can enter the MELVYL system from different campus libraries. MELVYL's goal is to have one union record for each distinct edition of a work. To promote this goal, the University's Division of Library Automation (DLA) has developed record merging algorithms that include author, title, place of publication, publisher, date, and pagination. Other data elements from the MARC record that are significant in distinguishing between different works or different editions of the same work have been added to the algorithm. This guide describes DLA's procedures for merging records, MARC fields and subfields used in merging, and bibliographic information used in merging, and provides examples of merged and nonmerged records. Records of books and in-analytic materials and records of periodicals are merged separately, and the procedures for merging records for these two formats are described separately. Some of the results of using the algorithm to merge different types of records are summarized, and it is concluded that these experiences with merging highlight how important it is to have standards for minimum record content and to use nationally- and internationally-assigned numbers for records coming into the catalog.
