We send files once a month to OCLC to update holdings. Chris Sharp will have more info on how that happens. We haven't had any issues with the file not being processed within a few days. We have had issues where passwords have expired or something else prevents the files from going through. We could do it more often under our contract with OCLC; but, a month works for our libraries.
PINES only updates holdings and doesn't delete since Evergreen doesn't report the last copy for a system in a consortial environment where we all have separate OCLC symbols. Each system is responsible for their own deletes and we have a report they use to help. In reality, we know that some libraries never delete their holdings. OCLC does have a new, free mini reclamation process that we hope to take advantage of again to keep holdings up to date. Elaine J.
