Adding these revised records would update and correct some errors in existing bibliographic records, but loading them might overwrite local notes and series practice. I would like to try loading around 100 records and see what happens. This would give us a test to see if problems result from the overlays. Let's begin loading these records as soon as possible. If there is concern about changing local series information, we could request that Marcive not change series information.
Many documents have on-line equivalents.
I would like to get the revised bibliographic records containing such information and links loaded so that they will overlay older bibliographic records which lack this information. If we have added MeSH headings locally, we would lose these when loading the Marcive updates. I would prefer not to continue doing this. We may see unanticipated problems with the updated bibliographic records for documents. We could ask to see some of the changes.
