OCLC staff will work with you to modify your current practices in ways that ensure delivery of up-to-date information about your collections. This will require a change in the frequency of your batchload to daily updates.
OCLC can create institution records (IRs) for your library. These IRs are not limited by format. While a library can get IRs for serials records, the holdings data elements still must be on LHRs. Institution records do not currently display in WorldCat Local, but this is planned as a future enhancement.
Yes. The amount of time required for cleaning up a library's OCLC data will vary from library to library, depending on the type and quantity of work required. Consult with your OCLC representative to discuss options for completing this work as efficiently as possible.
Local information that is present in your catalog, but not in WorldCat, will not display in the WorldCat Local interface. Consult with your OCLC representative about getting your holdings into WorldCat. This usually can be achieved through a retrospective batch load.
MeSH is currently not indexed for searching, but OCLC does plans to include MeSH from Medline metadata with the rest of the subject index searches later in 2008.
