WorldCat knowledge base documentation

Transition to the WorldShare interface

In order to serve our users better, the WorldCat knowledge base is transitioning all users from the WorldCat knowledge base module in OCLC Service Configuration to the WorldShare interface, Metadata tab.

For instructions you might need for the transition, see the Transition to the WorldShare interface page.

Examine methods to build your knowledge base

You will need to make a decision about the best way to add each of your electronic collections to your knowledge base. Start with this chart which shows the advantages of each method, and then proceed to expand the relevant sections:

Add ebook, serial, and other collections through the OCLC interface

Select an entire collection as represented in the global WorldCat knowledge base, or modify it to reflect your subset of titles and/or your coverage dates: Add or modify a Standard Collection

Search the Knowledge Base Using the WorldShare Interface

Select and Modify Your Collections Using the WorldShare Interface

Modify Your Collections Using File Download
Upload a special, niche collection that is NOT currently found in the global WorldCat knowledge base: Add a new Standard Collection (including print serial collections)

View the tutorials on creating Standard Collections

OCLC KBART template: Use this template to upload collections in the OCLC interface. Your spreadsheet must be saved as a .txt file before uploading.

Add serial collections through Pubget

Many of your collections can be added to the knowledge base through Pubget. Using Pubget is the easiest method for adding some of your collections and requires minimal maintenance:

  • Gather the vendor-supplied administrative user names and passwords for the e-resource providers you want to include in the knowledge base
  • Use the password given to you by OCLC to log in to Pubget
  • After you enter the credentials, Pubget and OCLC work together to add your holdings to the knowledge base, usually within two weeks time

Note: Pubget is limited to harvesting e-serials holdings from certain providers.  eBook holdings cannot be harvested. 

A list of e-serial providers currently available for harvesting can be found here.

Automatically add DDA collections and track purchases

We can help you implement your DDA program using your existing OCLC services and subscriptions.

OCLC works directly with some providers that can send us your library-specific DDA collection and when a purchase is triggered, the purchased title will automatically be moved into a purchased collection. Because we can automatically maintain a DDA and a purchased collection in two separate collections, you can easily track, mark, and customize MARC records per collection.

To get started: Follow the instructions to initiate auto-loading. Then, configure your settings.

Consortia and group members: You have specific considerations for sharing collections and for your initial set-up. Contact the OCLC implementation team for groups to guide you.

(See an overview of the DDA service: Options for implementing your DDA program)

Automatically add e-collections from EBL, ebrary, Elsevier, Ingram, and others

OCLC works directly with some providers to automatically add and maintain your library-specific collection metadata to your WorldShare Metadata instance.

See the providers we work with and the types of collections we can automatically load and maintain.  

To get started:

  • Follow the "Before you request" instructions to make sure your WorldShare account is ready.
  • Then, request the collections as described.
  • Once the collections are represented in WorldShare Metadata, configure the settings. You have options to display full-text links, output customized MARC records that include your URL, set and maintain holdings on the titles in WorldCat, and more.

Consortia and group members: You have specific considerations for sharing collections and for your initial set-up. Contact the OCLC implementation team for groups to guide you.

Add U.S. government document collections

FDLP libraries that want OCLC to add their government document collections/title metadata automatically must have access to WorldShare Metadata Collection Manager in the WorldShare interface and notify OCLC.

To request the autoload of your collections please follow the instructions for getting started in the "Government document collections" web-based document.

Once your collections have been loaded use this step-by-step guide to start receiving MARC records for your collections.

Map a holdings file from SFX, EBSCO, or Serial Solutions to knowledge base collections

SFX, EBSCO and Serial Solutions allow us to map holdings files exported from their services. Using these files, OCLC will attempt to identify and select corresponding knowledge base collections.

Since there is not always a 1-to-1 parallel between knowledge base providers, this is an iterative process whereby OCLC will map, review, identify new indexes, and map again in order to improve results. Each time we map your holdings file, you will be sent a report of what from your third-party provider we are able to match to WorldCat knowledge base collections. Please contact when you have submitted your holdings file, so that we can work with you to create the best results set.

Share collections with libraries in your consortium

Participate in Cooperative Management

Learn about cooperative management

Several users have requested the ability to contribute data changes to global knowledge base collections.  To that end, we are introducing cooperative management of global knowledge base data.  These features will be implemented only in the WorldShare interface in three phases over the next three releases.

Approve or deny global data changes

Phase one of cooperative management of knowledge base data is to introduce an approval process for the data updates that the knowledge base currently makes.

Contribute title changes to existing collections

Phase two of knowledge base cooperative data management allows users to contribute changes they have made to titles in their local version of a customizable global collection back to the global knowledge base collection so that other libraries may benefit from their work.

Add a new title to a global knowledge base collection

Phase three of knowledge base cooperative data management allows users to contribute new titles to customizable global knowledge base collections so that other libraries may benefit from their work.   

Delete a title from a global knowledge base collection

Phase three of knowledge base cooperative data management allows users to delete titles from existing customizable global knowledge base collections so that other libraries may benefit from their work.   

Add a new collection to the global knowledge base

Phase three of knowledge base cooperative data management allows users to add entirely new customizable collections to the global knowledge base so that other libraries may use them.

Set and maintain holdings in WorldCat

Synchronize titles in WorldCat so your holdings are always up-to-date and ensure that resources appear as held by your library (and are in your level-one relevancy group if applicable).

  • Go to Library Holdings - Maintain Holdings in WorldCat. Select the “yes” radio button. All collections will now have holdings set in WorldCat (except open access collections).
  • To turn off holdings for specific collections, expand the collection’s Holdings and MARC Records settings

NOTE: There is a delay of 7-10 days before holdings are set.

For detailed instructions, see the document: Maintain Holdings in WorldCat

Set up Google Scholar links

WorldCat knowledge base links and participation in Google Scholar's Library Links program
Libraries using OCLC's OpenURL link resolver (OCLC's integrated link resolution service) can complete settings in the WorldShare interface in order to include links from their WorldCat knowledge base collections in Google Scholar results.

I want to quickly connect my patrons to full-text in my discovery interface.

To enable full-text links in OCLC Service Configuration:

First, navigate to the My - Full Text and Open Access Links screen.
Check "Links from the WorldCat knowledge base to full text content" under Detailed Record. This will automatically select the settings for links to appear on the detailed record and on the brief record on the search results page. If for some reason you do not want links in search results, adjust the Search Results setting.

Additional documentation

OCLC number additions and corrections

The instructions for reporting OCLC number additions/corrections and this spreadsheet template for reporting OCLC numbers describe the information and formatting needed for OCLC to correct/add numbers to the knowledge base. Only the correct OCLC numbers are needed. Submit to OCLC support.

Link scheme values

The Link scheme values spreadsheet contains the values that are supported by the WorldCat knowledge base. The link scheme value instructs the WorldCat knowledge base how to create article links for a particular record or set of records. For libraries that wish to create one collection with content from multiple, different platforms, or if a library has an individual title that requires special handling, this value can be overridden on a per record basis. The value will be used when creating article links for a record instead of the collection-level link scheme value. Please Note: The field is optional and should only be used when it is truly necessary. OCLC Support can assist in picking the correct value to use.

We are a worldwide library cooperative, owned, governed and sustained by members since 1967. Our public purpose is a statement of commitment to each other—that we will work together to improve access to the information held in libraries around the globe, and find ways to reduce costs for libraries through collaboration.
