OCLC has released the WorldCat Digital Collection Gateway for CONTENTdm sites.
Here's an excerpt from the press release:
The WorldCat Digital Collection Gateway is available to all users of OCLC CONTENTdm Digital Collection Management software at no additional charge.
The WorldCat Digital Collection Gateway offers libraries a self-service tool to easily upload metadata from their unique digital content to WorldCat, the world's largest online resource for finding items held in libraries. Once the metadata is in WorldCat, libraries' digital collections are more visible and discoverable by Web searchers through WorldCat.org, WorldCat Local (including the ‘quick start’ version), Google, Yahoo! and other popular search engines.
"Libraries, museums and archives should do whatever they can to get their materials available online and expose their collections to users—wherever they are—on the Web,” said Roy Tennant, Senior Program Officer, OCLC Research. "The WorldCat Digital Collection Gateway is an easy and effective way to do this."
The Gateway has been piloted in 12 institutions. Since May, the pilot participants used the Gateway self-service tools to upload thousands of records from their CONTENTdm collections into WorldCat. Because they have used the Gateway to set up profiles for their collections, the pilot users' metadata will be regularly uploaded to WorldCat as they add to their digital collections over time.
