Stable Links for Library Resources

How to create stable links for online articles and books.

What is a stable link?

Stable links for library resources are links that can be reused, for example to link to an online article as a course reading.

In many library online resources, the URL (address) that displays in the navigation bar of your web browser is not a stable URL.  There are two potential problems:

  • The URL might be dynamic rather than persistent.  Dynamic URLs include session information that will expire and can't be reused.
  • The URL might not include EMU's proxy prefix.  The proxy prefix gives off-campus users an opportunity to login and allows the publisher to recognize authorized EMU users.

Create links that include the EMU Proxy and allow on and off-campus access to library resources:

  • The link must be a stable, persistent link. See What is a stable link?, above.
  • Do not add the proxy to freely available sites (such as free news or magazine sites) - the link will not work.

EMU Proxy for Off-Campus Access

When you use library resources on-campus, you will not usually see the proxy prefix in URLs for library resources.  However, the proxy prefix is required in order for a link to be stable and usable from off-campus.  The proxy prefix directs off-campus users to login and and allows the publisher to recognize authorized EMU users.

EMU's proxy prefix:

Some library databases will include the proxy prefix in persistent URLs that they provide; others will not. Before reusing a link from a library database, check to see if the proxy prefix is included at the beginning.  If not, simply add it to create a URL that will work from off-campus.  For example:

A "stable" URL from JSTOR:

Add the proxy prefix, or use the EMU Proxy Link Generator above, to create a truly stable URL that works from all locations:

Adding the proxy prefix does not give access to non-EMU users; since it directs users to use their my.emich login and password, only current EMU students, faculty and staff will be given access to library subscription resources.
