FAST (Faceted Application of Subject Terminology), an enumerative, faceted subject heading schema derived from the Library of Congress Subject Headings (LCSH), is now available as an experimental Linked Data service and is made available under the Open Data Commons Attribution License.

The FAST authority file, which underlies the FAST Linked Data release, has been created through a multi-year collaboration of OCLC Research and the Library of Congress. Specifically, it is designed to make the rich LCSH vocabulary available as a post-coordinate system in a Web environment.

“Linked Data” is an approach to publishing data on the Web which enhances its utility by making references to persons, places, things, etc. more consistent and linkable across domains.

The release of FAST as Linked Data provides FAST headings that support both human and machine access. FAST incorporates links to corresponding LCSH authorities. In addition, many of the geographic headings have links to the GeoNames geographic database.

“The response to VIAF (Virtual International Authority File) as Linked Data has been very positive,” said Lorcan Dempsey, Vice President, OCLC Research, and OCLC Chief Strategist. “We are now pleased to be making this very extensive resource available in this way.”

With the addition of FAST, the universe of library-oriented controlled vocabularies available as Linked Data is notably expanded. OCLC has previously released Dewey.info (http://dewey.info/), an experimental space for linked Dewey Decimal Classification (DDC) data, and also made available as Linked Data the VIAF a joint project that explores combining the name authority files of participating institutions into a single name authority service. Furthermore, the Library of Congress (see for example, http://id.loc.gov/) and several other custodians of important controlled vocabularies have released Linked Data versions of their schemes.

This release of FAST is the latest in a series of activities by OCLC to make FAST more accessible and useful. OCLC Research released mapFAST, a map-oriented interface that leverages FAST to present library resources based on the geographic focus of the content of material and made available the FAST Converter, a demonstration LCSH-to-FAST conversion tool. Most recently, OCLC Research has updated its Web search interface to FAST.

More information about FAST Linked Data is at http://id.worldcat.org/fast/. View a sample record and see the FAST activity page.

On Monday, OCLC launched the OCLC WorldShare Platform, a shared technical infrastructure that will support a growing number of OCLC services and applications. This platform will enable library developers, partners and other organizations to create, configure and share a wide range of applications that deliver new functionality and value for libraries and their users.

The OCLC WorldShare Platform facilitates collaboration and app-sharing across the library community so that libraries can combine library-built applications, partner-built applications and OCLC-built applications. This enables the benefits of each single solution to be shared broadly throughout the library community.

In the coming weeks, participants from platform pilot libraries will work with members of the OCLC Developer Network to help create and build new applications to populate the new OCLC WorldShare App Gallery, where users will be able to see available apps and install them into current work environments. Developers can showcase their creativity, partners can create add-on functionality and library staff can find practical, everyday solutions to streamline and enhance their workflows.

The first services built on this new technical infrastructure are Webscale Management Services, which have been rebranded as OCLC WorldShare Management Services, and include circulation, acquisitions and license management applications. Today, more than 30 libraries are already using OCLC WorldShare Management Services, and more than 150 libraries worldwide have committed to the new service since September 2010.

Over time, OCLC will bring together additional services and applications under the OCLC WorldShare name, including resource sharing, consortial borrowing, metadata management and other applications. OCLC’s currently deployed library management solutions will continue to be maintained and enhanced in line with member libraries’ ongoing requirements under their current brand names.

WorldCat will continue to serve as the name for shared data, including registries and the knowledge base, as well as discovery services such as WorldCat.org and WorldCat Local.

Finally, OCLC is taking the first steps in a migration to cloud computing for service delivery. OCLC currently operates data centers located in the United States. The first data center outside the United States will be available in the United Kingdom in early December. Additional data centers will be deployed in continental Europe, Australia and Canada in the coming year. Data centers around the world will support performance, reliability and scalability in OCLC’s increasingly global Cooperative.

A new A-Z journal list feature now available for WorldCat Local gives library users even more ways to find the journal or journal article that they’re looking for. Users can now browse a library’s collections with an integrated A-Z listing of available e-journals, made possible by the WorldCat knowledge base. The A-Z list completes the OpenURL resolver functionality available for WorldCat Local libraries: inbound and outbound linking and the A-Z list are included at no additional charge to subscribers.

Persistent facet selection

Now as you browse through results pages, the facets you initially select will stay selected until you do a new search or manually change them. This will save time for searchers who navigate from records to a results list using their browser "back" button.

Boolean updates

Thanks to member feedback, Boolean operators now work only when used in all caps (AND, OR, NOT). Lowercase versions of these words have been added to the Common Word Exclusion list:

  • English: a an and (lowercase) are as at be but by for from had have he her his how in is it not (lowercase) of on or (lowercase) that the this to was which with you

  • French: de la le les des un une

  • German: der das dass du er sie es wer wie mit am im in aus auf ist sein wird ihr ihre ihres als von mit dich dir mich mir mein sein kein wird

Anchored phrase searches

If you want to search for a specific phrase within a specific index , you can now use an equals sign (=) in combination with an index label. For example, the query ti=gone with the wind now searches for the anchored phrase “gone with the wind” in the title (ti) index. This will retrieve records containing exactly this phrase and only this phrase in the fields/subfields that are indexed for title search.

For regular phrase searching, you may also continue to enclose search terms in double quotes when using an index label in combination with a colon (:). For example, the query ti:”gone with the wind” searches for the phrase “gone with the wind” occurring anywhere within the fields/subfields that are indexed for title search and will therefore match on records containing, for example, “gone with the wind revisited” or “Margaret Mitchell’s gone with the wind letters.”


Databases added

New content is added on a regular basis. The central index now includes three new databases:

  • Oxford Handbooks Online from Oxford University Press

  • Oxford Scholarship Online from Oxford University Press

  • National Criminal Justice Reference Service (NCJRS) Abstracts Database from the U.S. Department of Justice (publicly available)

Six additional databases from EBSCO are now available remotely:

  • Criminal Justice Abstracts

  • Criminal Justice Abstracts with Full Text

  • Educational Administration Abstracts

  • Family Studies Abstracts

  • Historical Abstracts with Full Text

  • SocINDEX with Full Text

Full-text search coming soon
Full-text searching functionality is coming soon to WorldCat Local. This new feature will evolve as new full-text databases are loaded into the central index.

OhioLINK-OCLC Collection and Circulation Analysis Project 2011

This new report describes a collaborative project between OCLC and OhioLINK that examined circulation in academic libraries, and includes an overview of data publicly available from the activity. The size of the combined collection and the number and diversity of participating institutions make this by far the largest and most comprehensive study of academic library circulation ever undertaken.

The goal of the study, which was limited to books and manuscripts, was to better understand the usage and collecting patterns within OhioLINK libraries.

The report provides:

  • an overview of the study and its outputs, including its purpose, goal, and distinctive aspects; how the data was gathered; and the location, form, and overview of derived data;
  • a description of how the data was analyzed, presented, and made available, both at the institutional level and for the collection of participating OhioLINK libraries;
  • uses for the data, conclusions, and a glossary; and
  • an external appendix that provides a rich set of supporting materials related to the development and conduct of the study.

In addition to the data-analysis files described in the report, the base data file of circulation records for nearly 30 million OhioLINK books and related WorldCat bibliographic data also is being made publicly available under the Open Data Commons Attribution license (an open license) to download for study and research.

OhioLINK Collection and Circulation Analysis—Circulation Data



A new report released by OCLC describes OCLC's steps to make it easier to find itmes in WorldCat and get them from OCLC member libraries.

The report begins with a review of WorldCat's unprecedented growth since 2008, largely from metadata contributed from national libraries and union catalogs from outside North America. This rapid growth has challenged OCLC's programs for managing duplicate entries and library location (holdings) information.
OCLC's 2010 implementation of new duplication detection and resolution (DDR) software helped to resolve the issue of true duplicates in WorldCat; however, WorldCat quality needs to be further strengthened.  The paper describes a special project - GLIMIR- and other WorldCat quality improvement projects scheduled for FY2012. GLIMIR's principal benefits will be to improve the clustering of WorldCat records and holdings for the same work, thus reducing the complexity of search result displays and supporting more reliable linking to local library catalogs.  The paper concludes that it is necessary to reinvent OCLC's long-standing and successful, but English-language-centeric approaches to metadata creation and data quality management for the realities of the increasingly multilingual, multinational OCLC cooperative.

OCLC and Ingram Content Group have launched a new e-book service option that provides libraries and their patrons short-term access to e-book content that is not in a library’s collection through WorldCat Resource Sharing.

The new e-book service option increases the amount of content available through WorldCat Resource Sharing. Through the collaboration, e-books from Ingram’s MyiLibrary e-book collection will be available to participating libraries and their patrons for a nine day period. The option will be available in ILLiad within the next several months. E-book loans are fee-based, set at an average of 15 percent of the MyiLibrary price set by the publisher for access to the e-book. The fee is managed through the WorldCat Resource Sharing interlibrary loan fee management (IFM) feature that supports payment of resource-sharing services through the library’s OCLC invoice.

The addition of Ingram’s MyiLibrary content provides access to more than 50,000 e-book titles, and is growing daily. Content from the world’s leading publishers, such as Taylor and Francis and Wiley are currently available through the new short-term access option. Records for all titles have been added to WorldCat under the symbol IDILL, so users will find these titles when they search the WorldCat database via WorldCat.org, WorldCat Local, WorldCat Local “quick start” and FirstSearch. Interlibrary loan staff can then facilitate access to the available titles by requesting them from IDILL. View the list of available e-book titles.

To support the new and growing e-book access program, Ingram will send “Conditional” messages to request that borrowing library staff take an action such as enabling IFM or adjusting their Maxcost setting to accommodate the cost of an e-book loan. Ingram will place the link to the e-book in the new field “Alert” to notify the borrower immediately that the request has been filled and to alert the library that they will have nine days from the date the e-book is “shipped” to use the link before it expires.

This short-term access option delivers e-books to users quickly, so they can begin to use requested titles right away. Once a request is updated to “shipped” status, it is immediately available for use with no delays for shipping, or the time required to pick up a requested print title. This supports the way many users make use of e-books to obtain specific parts of information for research. For example, often a chapter or section of an e-book is all they need to use. The MyiLibrary interface allows users to search the full text of titles to quickly identify the sections they need.

Libraries mark 40 years of online cooperative cataloging with WorldCat

Today marks the 40th anniversary of the launch of WorldCat, the world’s most comprehensive database of resources held in libraries around the globe.

On August 26, 1971, the OCLC Online Union Catalog and Shared Cataloging system (now known as WorldCat) began operation. That first day, from a single terminal, catalogers at Ohio University in Athens, Ohio, cataloged 133 books online. Today, WorldCat comprises more than 240 million records representing more than 1.7 billion items in OCLC member libraries worldwide.

“We congratulate the thousands of librarians and catalogers around the world who have helped to build WorldCat over the past 40 years keystroke by keystroke, record by record,” said Jay Jordan, OCLC President and CEO. “We who work at OCLC are proud to have been a part of this remarkable story, and I want to thank our member institutions and employees for the years of dedicated effort that helped build this unique resource. Fred Kilgour’s vision – improving access to information through library cooperation -- is every bit as vital today as it was in 1971. This anniversary is an important milestone in a shared journey that, I believe, will continue for many decades to come.”

WorldCat is a database of bibliographic information built continuously by OCLC libraries around the world. Each record in the WorldCat database contains a bibliographic description of a single item or work and a list of institutions that hold the item. The institutions share these records, using them to create local catalogs, arrange interlibrary loans and conduct reference work. Libraries contribute records for items not found in WorldCat using OCLC shared cataloging systems.

“In retrospect, I have to say that in those early days, I don’t think we really understood the enormity of the system that we were embarking upon, much less did we consider what the future possibilities might be,” said Lynne Lysiak, who had just started her career at Ohio University Libraries when WorldCat first went online, and is now retired. “As OCLC forges ahead now with WorldCat Local and cloud-computing developments, they are embarking on a new era and suite of services for libraries and their users. It’s an exciting time.”

“OCLC cataloging and resource sharing services and our library management systems continue to help libraries improve their productivity, save money and improve access to their collections,” said Mr. Jordan. “Against a backdrop of continuous technological change, WorldCat and the OCLC cooperative have continued to grow.”

Since 1971, 240 million records have been added to WorldCat, spanning more than 5,000 years of recorded knowledge, from about 3400 B.C. to the present. This unique collection of information encompasses records in a variety of formats—books, e-books, DVDs, digital resources, serials, sound recordings, musical scores, maps, visual materials, mixed materials and computer files. Like the knowledge it describes, WorldCat grows steadily. Every second, library members add seven records to WorldCat.

Once records have been added to WorldCat, they are discoverable on the Web through popular search and partner sites, and through WorldCat.org.

Records entered into WorldCat since 1971 have been continuously migrated, reformatted and updated to conform to newly issued cataloging standards. They have been touched and enhanced hundreds of times by librarians around the world and by OCLC staff and automated systems.

The first OCLC cathode ray tube terminal was the Irascope Model LTE, which was manufactured by Spiras Systems. OCLC deployed 68 LTES, one of which is now on permanent display in the National Museum of American History, Smithsonian Institution, Washington D.C., and another in a new OCLC Museum dedicated today in Dublin, Ohio. The LTE was connected to OCLC via a dedicated, leased telephone line from AT&T; message traffic moved at the rate of 2400 baud (2,400 symbols per second).

People can now use their mobile phones to access WorldCat via WorldCat Local, where 4G wireless downloads are 2,500 times faster than the original OCLC network. Wired networks are now 416,000 times faster.

OCLC has decided to discontinue new and renewal sales of Electronic Collections Online e-journals and will move existing content from the service to archive-only access on February 1, 2012.


This move is a continuation of a strategy announced in March 2010 to discontinue hosting and reselling content in order to focus resources on developing superior discovery-to-delivery of content on vendor-neutral services. Since then, OCLC has transitioned most of the content previously available on the FirstSearch service to other providers and have expanded access to the remaining content through WorldCat.org, WorldCat Local and WorldCat Local “quick start.” Transitioning Electronic Collections Online content to archive-only access further supports this strategy.  


Effective immediately, OCLC will no longer accept subscriptions or renewals to Electronic Collections Online e-journal content, and OCLC will stop adding new content to the service on February 1, 2012. Libraries may continue to provide access to the content from their past Electronic Collections Online e-journal subscriptions by maintaining an access account to the service archive. For an annual access fee, libraries can continue to provide access to the electronic articles included in their past subscriptions.


Authenticated users may continue to search the Electronic Collections Online bibliographic database on FirstSearch, WorldCat.org, WorldCat Local and WorldCat Local “quick start” and link to the full-text articles they identify through their searches. In addition, they may include the Electronic Collections Online database in a single search across multiple databases within these services. Articles in Electronic Collections e-journal subscriptions will continue to be available to authenticated users as a source of full-text linking within the service as well. Per-article purchase of Electronic Collections Online e-journal articles will end on January 31, 2012.


OCLC has informed subscribers of this change via a letter mailing the week of August 8.  This letter refers them to OCLC Order Services (orders@oclc.org) for additional information and to request access to the Electronic Collections Online archive.


As OCLC moves forward with the development of cloud-based services, OCLC staff will continue work on behalf of  members to provide access to as much quality content as possible through these services. 


Please contact Brian Cannan cannanb@oclc.org with any questions about this transition.


OCLC is pleased to announce the release of CONTENTdm 6. CONTENTdm now offers a complete redesign for the end-user experience along with new website configuration tools that enable digital collection administrators to easily customize their collections website without programming expertise.
