Update

Although the records do have local system numbers, and could be coded for updating, the Summit systems will be moving to OCLC Local in a short while, so we will not receive updates from the Summit system.

OCLC Numbers

Most records store the OCLC number in the 001 field. We should copy these to the 035 so they can be captured and stored as OCLC numbers in the Open Library record.

take the number from the Summit 001 field, strip off "ocm" at the beginning if it's there. If what remains is all numeric, create an 035 $a with "(OCoLC)" + the number from the 001.

001 2507014 --> 035 $a (OCoLC)2507104

001 ocm16535371 --> 035 $a (OCoLC)16535371

Some OCLC numbers will have leading zeroes. It appears that they can be retrieved on WorldCat both with and without the zeroes. I don't know if it makes a difference in other systems... so I guess we shouldn't remove leading zeroes unless we discover a reason why that would matter.
