WorldCat Local Search Results / WorldCat Discovery Search Results and Detailed Views

Primary Links

WorldCat Discovery displays primary links on the search results and is exposed on the detailed view of a record.

Links from the WorldCat knowledge base to full text content.

Configure link display order in the WorldCat Discovery section of Collection Manager Settings module. See WorldCat Discovery for more information.  

View now links are only returned for the following content types:

  • Journal (Full Text)
  • e-Book
  • Audio
  • Image
  • Video

 Notes: 

  • The following content types will not return a view now link:
  • The content type of the WorldCat record must match the content type of the title in WorldShare Collection Manager to surface a link. The date range of the record in WorldCat must fall inside the date range of the Collection in Collection Manager.
Links from LHRs

Enable LHRs in the OPAC Statuses, Locations and Circulation Policies module.

Links from the LHR will display when a link is contained in the 856 $u field.

Links from Local OPAC

Local OPAC link options:

  • Monograph (default type): Anything that is not in one of the groups below
  • Serial: Leader value of serial, not web-based
  • Article: Leader value of article
  • E-Serial: Leader value of text serial and cataloged as an internet resource. Also Leader value of Computer File and cataloged as an internet resource and serial
  • Mass digitized electronic content: Only assigned to non-article, WorldCat Records with the same original and alternate types before bibliographic matching. Content is defined as mass digitized if one of the following is true:
    • The MARC field 029 has any of the following values:
      • DGCNT
      • CNTNT
      • CNTCOLL
      • DGCOLL 
    • The MARC field 040a has the value as OCLCE

       Note: Central Index articles inherit the item type from the parent journal.  If the representative record of the ISSN associated with the article is a mass-digitized item, the article will also be considered a mass digitized item. 

  • All other electronic content: Any other electronic content such as e-books, e-computer files, e-audio, e-visual materials, websites, and e-maps
Links from WorldCat record 856 and 956 to open access content/free content

WorldCat Discovery uses WorldCat MARC Indicator 40 to inform availability link displays and uses WorldCat MARC indicator 41 or 42 to inform description displays.

Links from non-WorldCat Record 856

Vendors will sometimes provide OCLC with 856 links for Central Index records. These 856 links will not appear in the OCLC record, but are mapped from the Central Index. Checking this box will allow those vendor-provided links to appear in your WorldCat Discovery instance, and will display as an Access Online button. It is important to remember that these links are not passed through the institution's proxy and are not matched with knowledge base holdings. Therefore, users are likely to hit a login or pay for access page, and will not reach a full text article.

Links from DOI

Users can access open content using DOI full text and open access links provided by Unpaywall. For more information see, https://unpaywall.org/faq. When enabled, DOIs will inform the Access Online action on search results, detailed records, and Course Reserves. DOIs are compared to Unpaywall data to ensure that only DOIs leading to open access content display. When a DOI leads to a downloadable PDF, a View PDF button appears on DOI links enhanced by Unpaywall. When it cannot be determined that a DOI link informed by Unpaywall leads to a PDF, a link to Access Online <insert DOI> appears. If a DOI is not present in Unpaywall, the DOI will not inform the Access Online button, but will continue to display in the Description of detailed records.

 Note: If a user encounters a link from Unpaywall that does not lead to Open Access, you will need to contact Unpaywall directly to have the link corrected. Please see, Tips to identify elink sources in WorldCat Discovery to determine if the link in question is a DOI link.

Other Links

WorldCat Discovery collapses the display of other links on the detailed view of a record.

  • Links from the WorldCat record 856 to non-open access content/non-free content.
  • WorldCat Discovery uses MARC Indicator 40 to inform availability displays.
  • WorldCat Discovery uses MARC Indicator 41 or 42 to inform description displays.

Interface Display

Determine whether to display all primary links or the first primary link only on search results and Course Reserves.

Display first primary link only

The first primary link will display on search results and Course Reserves for all material types except when an e-serial has multiple full-text access options. 

  • When an e-serial has multiple full-text access options, users will see all alternate access options for that record from the search results page. This will happen regardless of whether an institution has selected to display all primary links or only the first primary link. The display of all alternate access options ensures users have access to alternate links that provide different ranges of full-text coverage for an e-serial.

An Alternate Links textual link will display immediately below the primary access option button. This offers users the option to choose either:
    •    The primary access option button to connect with content at the first primary link.
    •    The Alternate Links textual link to open the drawer that presents all primary links.

Display all primary links

Determine whether to display all primary links. If configured, when an item has multiple e-link access options available, a drawer displaying all primary links will open for all material types when the user clicks the full-text button.

WorldCat Local Detailed Record Page

Choose whether to display the following links in the detailed record view of WorldCat Local.

  • Links from the WorldCat knowledge base to full text content.
    Configure link display order in the WorldCat Discovery section of Collection Manager "Settings" module.

     Note:  Links from the WorldCat knowledge base may contain open access/free content.

  • Links from LHRs 
    LHRs can be enabled on the OPAC Statuses, Locations and Circulation Policies module.
  • Links from the WorldCat record 856 to non-open access content/non-free content.
