The features libraries need

Whether you seek ease of learning and use, or the potent shortcuts of the cataloging power user, Connexion has you covered.

  • WorldCat searching

    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. Dropdown menus list available indexes, eliminating the need to memorize index labels. Experts can search via a command line using index labels and search strings.
  • Edit and export records in various formats

    Full record editing is available in either MARC or Dublin Core (Dublin Core editing available in Connexion browser only). Connexion browser users can export in one of several formats: MARC 21 (MARC-8 character set), Dublin Core HTML or Dublin Core RDF. Connexion client users can export in MARC-21 format (MARC-8 or UTF-8 Unicode character sets) or Dublin Core Qualified, Dublin Core Simple, and MARCXML format (UTF-8 Unicode character set).
  • Bibliographic institution records

    Create and maintain copies of your library's institution records which may contain additional cataloging data, such as local call numbers, holdings locations within the institution, or local or copy-specific notes.
  • Catalog using worldwide scripts

    Search WorldCat and edit bibliographic records using languages written in Arabic, Bengali, Chinese, Cyrillic, Devanagari, Greek, Hebrew, Japanese, Korean, Latin, Tamil, and Thai scripts.
  • Constant data

    Store and apply boilerplate text or data values to ensure speed and consistency in record editing.
  • Add original records

    Use blank workforms or derive data from existing records for original MARC or Dublin Core (Connexion browser only) cataloging. Let Connexion also create a basic record automatically for electronic resources. There's no size limitation, so your records can be as comprehensive as you want.
  • Dynamic control of authorities

    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. Other Connexion users worldwide can tell that the linked headings in the bibliographic records match those in the authority records.
  • Save file

    Save records in process, and search your save file using various indexes. Set a status on your in-process records to locate them quickly and search the file using various indexes. Choose between using an online save file stored at the OCLC host or a local save file stored locally at your library (Connexion client only).
  • Keep your library holdings up-to-date

    Accurate holdings information you maintain with Connexion helps Internet searchers everywhere find your library and the things you own through WorldCat holdings also help you to analyze your collection and compare it to others, using Collection Evaluation and help thousands of libraries keep materials moving through the WorldCat Resource Sharing system.
  • Label printing

    View, edit, and print catalog labels directly from displayed bibliographic records using the OCLC Cataloging Label Program (with Connexion browser) or directly from within Connexion client.
  • Fast access to institutional names

    In Connexion's holdings and 040 field displays, simply hold your mouse pointer over an institutional symbol to view the full name.
  • Link to RDA Toolkit

    In Connexion browser or Connexion client 2.30 or higher, if you subscribe to the RDA Toolkit, you can enable field-specific access to the guidelines in the online Toolkit from displayed bibliographic or authority records using either IP authentication or entering your RDA Toolkit user name and password.

  • Classify

    Use a command Classify on the Edit menu to automatically supply a Dewey or Library of Congress classification number in a displayed record for a book, DVD, CD, or other material type in a field you specify. The new command uses the prototype, FRBR-based Classify Web service to provide a classification number from a WorldCat record with a matching standard number in this order: OCLC number, ISBN, ISSN, UPC, LCCN.

    Context-sensitive help is ready on every screen, and Quick Tips within Connexion browser remind you on best use of interface components. Tutorials and training are always available in Connexion training.
