Linking to Library Resources

Proxying | Persistent URLs

You can create links to library resources to include in online syllabi, to list in paper syllabi, or to post in Moodle course pages. Below is information about proxying resources for off-campus access and creating persisitent URLs.


Most of the library's online resources are restricted to users from the Gustavus community. Authentication is provided by IP. For off-campus users to be authenticated, databases are channeled through a proxy server. This prompts users with an unfamiliar IP for a login (their library barcode and last name), then assigns them an IP recognized by our database providers. In order to connect users to the proxy server, urls for databases are modified.

To make a resource accessible from off campus, copy the URL for the resource, then insert the following proxy server script at the beginning of the URL:

For example: The stable link to a JSTOR article might look like this:

Simply insert at the beginning of the URL, so the link looks like this:

Access will seem the same from on campus, but off campus users will be prompted for a login.

Persistent URLs

What is a PURL?
PURL stands for Persistent Uniform Resource Locator. In other words, a persistent URL. Often, databases with full-text content may have links that constantly change - making it impossible to "bookmark" an article. A persistent URL is one that will be stable and unchanging.

What databases offer PURLs?
The following databases or vendors offer PURLs:
EBSCOhost, JSTOR, Project MUSE, PROLA, ProQuest, Thomson/Gale, and PubMed Central. Others may also be available.

What if my favorite full-text database does not offer PURLs?
You may wish to put that item on reserve in the library. Click here to learn more about placing items on reserves.

EBSCOhost databases
EBSCOhost offers several databases including Academic Search Premier, Business Source Premier, Communication and Mass Media Complete, and others. These databases include extensive full text coverage of many scholarly publications.

To link to EBSCOhost articles:

  1. Locate the article in the respective database.
  2. Click on the title of the article in the results page to retrieve the article's citation.
  3. In the Tools section to the right of the citation, click Permalink to display the persistent link.
  4. Copy the persistent link, replace the domain with the proxied domain, and paste it into your syllabus.

JSTOR is an archival database and does not include current journal issues, but provides complete full-text back files for 350 journals from more than 25 academic disciplines. All journals are fully searchable or available for browsing.

Project Muse
Project MUSE provides full text electronic access to over 100 scholarly journals in the humanities, the social sciences, and mathematics.

All article level URLs in MUSE are stable, and adhere the following format: volume number)/(volume#.issue#)(primary author's last name).html

For example: ...for the article "Through the Looking-Glass: Reading Warhol's Superman," by Bradford R. Collins And David Cowart, in Vol. 53, issue 2, of American Imago.

To ensure access to off-campus users, insert at the beginning of the URL.

PROLA is the American Physical Society's Physical Review Online Archive. It includes the content of Physical Review from 1893 to five years ago, Physical Review Letters back to 1958, and Reviews of Modern Physics back to 1929.
