Yes. You can upload the metadata from your CONTENTdm server to WorldCat using the free Digital Collection Gateway service. Each time you upload metadata to WorldCat using the Gateway, you are provided a WorldCat Sync report with the OCLC numbers of the records in WorldCat that correspond to the items in your CONTENTdm collection. You can use the Connexion client and the list of OCLC numbers from the WorldCat Sync report to create a local save file of MARC records from WorldCat to load into your local system. If your ILS supports it, OAI can also be used to harvest from CONTENTdm into your ILS.
