Linking to Library Resources

Off-campus access to the Library's licensed resources is restricted to current students, employees, and faculty with NetIDs. Patrons with GuestIDs will not have access. This should be the only major restriction to linking directly to licensed resources.

Instructors can usually assume that if the Library has a database or journal available in electronic format, they can point to it or its articles for a class. The Library always tries to secure the rights to use materials in the classroom when negotiating licenses. (Harvard Business School publications are the one major exception to this rule. Although they are available electronically through the Library, they may not be used in classes without additional permission. This limitation is clearly indicated on each article.)

However, providing copies of articles by printing them out or putting PDFs or other electronic documents on a Blackboard site for download − rather than making direct links to the articles within the licensed database or journal − is another matter. Check the terms of use on the journal’s Web site or the "Terms of Use" button in the E-Journal record to look up the general license terms for an individual title or database.

It is important to note that the information in the “Terms of Use” button is for all titles from the supplier of the electronic copy. Individual journals or articles may have more restrictive or more generous policies; check the “Terms and Conditions” section of any electronic journal, as well as the copyright notice on an individual article, to see if they include permission to include articles on course Web sites, in the course reserve system, or in course packs without having to pay additional permission. Directly linking to articles within a licensed database or journal (except for Harvard Business School publications) is often the surest way to include them without the need for additional permission.

Cornell-restricted databases and e-journals

You can bookmark or link to databases and e-journals, but because of the authentication process necessary to access restricted resources, to identify yourself as a Cornell user from a computer outside the Cornell network, your links need to be prefaced with:

Links or bookmarks with in them should not be used, because they bypass the authentication server and will not work consistently.

To find the correct URL for linking, find the resource in the online catalog, Find it!, or Find e-Journals.

  • Windows users: Right-click on the resource’s link and choose Add to Favorites (for Internet Explorer) or Bookmark This Link (for Firefox).
  • Mac users: Left-click on the resource's link while holding the Ctrl key and choose Add Link to Bookmarks (for Safari). These links can be added to web pages and Blackboard course sites.

Individual articles in a licensed journal

Articles can be difficult to bookmark or link, since not all publishers offer permanent URLs. Even if a permanent URL does exist, it may not be obvious what it is because different journals have different methods for constructing permanent links. On journal Web sites, some providers include permanent links to specific articles, sometimes identified as OpenURLs or DOIs (Digital Object Identifiers). Other providers give information on how to build a permanent link from their systems.

Regardless of the exact form of the permanent link, access to licensed journals is normally restricted to Cornell users. Because of the authentication process needed to access restricted resources, your links need to be prefaced with:

To link to an article with a DOI:

In addition to the, add the following:, making the whole prefix:

For example, if an article had the following DOI: doi:10.1038/nature04674, the link would be:

To link to an article with another type of permanent URL:

If the article does not have a DOI but the database or journal provides another type of permanent link, use:

For example, to link to an article with a permanent link of, the URL that will allow both on- and off-campus access is:

If the database does not provide a permanent link, try using the link provided in the browser, but please be aware that this link may not always work.

Note: It is important to test your links from off-campus after creation. If they do not work, make sure there are no extra spaces or punctuation in your URL and verify that the library has licensed access to the article. If the link is correctly formed and you should have access and you are still encountering difficulties, contact LIBGATEWAY-L.

OpenURL links

If you are using a service outside of Cornell’s regularly licensed resources that asks for the library’s OpenURL resolver to link to articles (such as the social bookmarking service Connotea), you can use the following: For all resources besides Connotea, please e-mail LIBGATEWAY-L so that our IT department can add the service to our link resolver. After this is completed, you will be notified and you should be able to use the service.
