The metadata in library catalogs makes library resources findable and accessible to library users. Library staff members constantly enrich WorldCat records with new and corrected information through the OCLC Cataloging and Metadata Subscription (previously the OCLC Cataloging Subscription), making these records the industry standard for quality. Partner content providers also add records to WorldCat—sometimes before a resource is published—so library users can find the information they need as soon as it’s available.
By sharing high-quality library metadata and bibliographic records with each other, librarians have dramatically reduced the time they spend on original cataloging. Between July 2015 and June 2016, OCLC member librarians copy cataloged 93% of their items from WorldCat, saving an average of 10 minutes per title. These librarians copy cataloged 18,266,511 titles during that year, so they saved around 3 million hours of time, collectively.
“High match rate...”
“We are totally dependent on our high match rate for cataloging records in WorldCat. If we had to do original cataloging for even a fraction of our new materials, we'd have no time to devote to the local projects that, frankly, have a much higher value in the long run.”

“Made our heritage visible...”
“Importing more than 10 million records into the WorldCat database has helped our universities to achieve an important goal: it has made our heritage visible internationally and enhances cooperation with libraries on a global scale.”

Built for librarians by the library community
With more than 45 years of continuous contributions, maintenance and improvements by thousands of librarians, library staff members and partner organizations, WorldCat contains data that point to electronic, print and digital information resources in libraries around the world. WorldCat helps libraries share the world's collected knowledge to fuel learning, research and innovation. And it grows larger and more valuable every day.
Provide access to knowledge.
If a library’s materials can’t be found, they can’t be used. WorldCat gives people the ability to view library collections from anywhere in the world, giving them access to a rich assortment of information much deeper than what can be found through a basic internet search. WorldCat plays an important role in getting library resources in front of people both inside and beyond the library on the popular websites where they begin their searches. Librarians can connect library users to library resources by adding WorldCat records into their existing catalogs or through FirstSearch, WorldCat Discovery and WorldCat.org.
“Natural search processes...”
“With WorldCat, library collections are globally integrated into the fabric of the web. Through natural search processes and the social networks people love, users find their way back to their local library.”

“In the old days, people had to consult dozens of reference works—and still they would have incomplete information. The need for a one-stop shop for discovery grew incrementally. A need, a wish, which became a requirement… Because the more libraries, the more content, the more visibility. And that is what we want.”

Share your collections.
WorldCat provides the data that power discovery of library resources and make library collections visible to the largest resource-sharing community in the world. Since WorldCat is the foundation of WorldShare Interlibrary Loan, libraries can easily see the resources available from other libraries, borrow directly from them and share their resources to meet users' needs. WorldCat also allows borrowing libraries to link users directly to articles provided by lending libraries, giving users the instant access they expect.
“See the content we have...”
“Patrons at other libraries can see the content we have [in WorldCat], and those libraries are requesting to borrow that content from us. Because we're a growing campus, we have been a net borrower for many years. Now we're a net lender—everyone out in the world can see our electronic content, and that's been a really great change”

“Visible to many...”
“WorldShare Interlibrary Loan brings together the collection inventories of a lot of libraries [through WorldCat], thereby making them visible to many, including the unique stocks of the Bavarian State Library.”

Prove your value.
Librarians increasingly rely on data to make decisions about the library’s collections and services and to justify those decisions to library stakeholders and funding organizations. WorldCat helps librarians compare their collections through WorldShare Collection Evaluation to gather the data they need to analyze their collection development choices. Librarians can compare their analysis to their own usage and circulation statistics through WorldShare Report Designer to make decisions about the library’s priorities. In addition, Sustainable Collection Services uses WorldCat to help libraries manage shared print collections.
“Support student learning…”
“Certainly, our shelves have more materials than we would like them to have, which makes it difficult to expand... . [This SCS deselection project] gives us a better opportunity to have space where we can collaborate together to support student learning.”

“It’s only by making sure that our records are up to date and synchronized fully with WorldCat that we have the ability to do a collection-level analysis across the community, which will enable us to make decisions … [to] get best value from our collective operations as a research library community.”

Make your collections visible.
Data about library collections, which house some of the most authoritative and unique resources in the world, is difficult to share directly from independent library catalogs. The collaborative nature of WorldCat helps libraries take advantage of linked data opportunities to lessen their workloads and to increase their online presence and discoverability. OCLC provides data services and downloadable data sets that help programmers and linked data practitioners create and improve their own applications with WorldCat data.
“Work with libraries...”
“As a major data hub, OCLC is well placed to develop linked data services for the library community, and they have made many far-sighted moves over a long period. What I welcome most of all is their willingness to work with libraries to understand how they can help us meet our goals.”

“Promise of linked data...”
“You only have to store and index locally the fields that people want to search right then and there. The promise of the linked data universe is that we could go out and get all of that other stuff from somewhere else, live time, on the fly.”

WorldCat brings together information about collection items, electronic resources and the libraries that make them available.
A bibliographic catalog
Everything that’s available through the library, including books, videos, photos and unique objects
A knowledge base
Connection to the library’s e-resources with options for automatic record updates
A registry of library profiles
Information about the library itself, including location, hours and services provided
“Don’t have to micro-manage...”
“The biggest benefit for me has been the time savings. I don’t have to micro-manage my electronic collections and holdings; I used to literally add titles one by one, in some cases. If I know this is happening automatically, I don’t have to worry about it.”
