Accelerate copy cataloging

Connexion allows you to simply search for matching records in WorldCat®, edit the record, set your holdings, export your records and print labels, if desired. You can also create and maintain copies of your library's local holdings records, which may contain additional data, such as local call numbers, holdings locations within the institution or local or copy-specific notes.

Library shelf signage

Create original MARC records

Connexion is the definitive tool for OCLC member institutions to perform original cataloging, adding records for new resources to WorldCat's global collective. With Connexion, you can check WorldCat to see if a record or title exists, create a new record, validate the record and export it individually or with other records you've created.

Connexion offers flexible searching using derived, numeric and phrase options in over 90 indexes of Arabic, Armenian, Bengali, Chinese, Cyrillic, Devanagari, Ethiopic, Greek, Hebrew, Japanese, Korean, Latin, Syriac, Tamil and Thai script data. Drop-down menus list available indexes, eliminating the need to memorize index labels. Experts can search via a command line using index labels and search strings.

You can search headings in a bibliographic record with the touch of a button and link headings to the associated authority records so the bibliographic record will automatically update if the authority record changes. You can also let other Connexion users worldwide know that the linked headings in the bibliographic records match those in the authority records.

Choose the interface that fits your needs

There are two ways to access the power of Connexion: a Web browser-based interface and a Windows® desktop application. Which interface you use depends on the unique needs of your library and cataloging staff. You can use both if required; consistency in presentation ensures that users can move back and forth between the interfaces with a minimum of effort.

Connexion browser

Choose the Connexion browser if you want a browser-based interface that requires no special software to install and is available from any Internet-enabled PC.

Learn more about Connexion browser

Connexion helps make cataloging available more places and for more people by way of its Web interface. The Connexion browser is utilized like any website through a standard browser, such as Microsoft Internet Explorer or Mozilla Firefox.

Key functionality

The interface provides all the advantages inherent in a Web view—it's easy to learn, navigate and use. Browser-based functionality ensures that you're always using the latest version—no software updates are required.

Some Connexion functionality is currently available only from the browser version:

Note: Certain Connexion functionality, such as macros, offline cataloging, batch processing and cataloging using non-Latin scripts (Arabic, Armenian, Bengali, Chinese, Cyrillic, Devanagari, Ethiopic, Greek, Hebrew, Japanese, Korean, Syriac, Tamil and Thai), is available only in the Windows-based Connexion client.

A detailed comparison chart is available to help you compare functionality in the Connexion browser and Connexion client, point by point.

The Connexion client provides much of the same cataloging functionality as exists in the browser interface while adding productivity-boosting enhancements, including macros, additional keyboard customization—you can perform all navigation and cataloging actions using assignable key combinations—and integrated label printing. In addition, you can work offline using client local files and batch processing to send your transactions to OCLC. The Connexion client supports Arabic, Armenian, Bengali, Chinese, Cyrillic, Devanagari, Ethiopic, Greek, Hebrew, Japanese, Korean, Latin, Syriac, Tamil and Thai scripts, with interface language choices of Chinese (Simplified), Chinese (Traditional), English, German, Japanese, Korean or Spanish. Individual users logging onto a shared workstation can maintain their own settings within the application.

System requirements

Software Hardware

32-bit and 64-bit versions of Windows Vista, Windows 7 and Windows 8/8.1 are supported by Connexion client version 2.50. In addition, the client requires that you have Internet Explorer 5.5 or higher installed on your workstation, but it does not need to be your default browser.

See specifications suggested by Microsoft for your version of Windows.

More detailed information on system requirements is available in the Getting Started guide.
