How does OCLC overlay matching work?
- Article Type: General

Description:
How does the oclc_server program match the input record against existing records for overlay purposes?
Resolution:
The oclc_server program reads column 9 in the $alephe_tab/tab_oclc.
The value in the $alephe_tab/tab_oclc column 9 is a match routine label, as specified in the $data_tab/tab_match. This tab_match routine is what it uses for matching. Reference: "How To Load OCLC Records into ALEPH".
For authority records you could have this in the xxx10 tab_match:
OCLC match_doc_uid I-LCC
or
OCLC match_doc_uid I-010
-- depending on the name of the Direct index you have built for the 010 field.
