A DOI (Digital Object Identifier) acts like a persistent URL. If your article has a DOI (for example, doi: 10.1525/aa.2000.102.4.916) you can find the abstract/full-text of the article by adding a URL prefix to the DOI: So the URL for the example DOI would be


Dynamic vs Persistent

When you look at a full-text article in a library subscription database or at a publisher's website, the URL associated with that article is either dynamic or persistent.

A dynamic URL means the the URL was created at the time you did the search in the database that eventually brought you to the article you are viewing. A dynamic URL is temporary and usually will not work when copied and tried again. So if you provide the URL to others (as in a research paper reference list, in a syllabus, in SAKAI, etc.) they will not usually be able to access the information.

A persistent or durable URL will return you to the same article every time. Some vendors do a very good job of providing a persistent/durable URL, others do not. This creates a problem when you need to provide a persistent or durable URL to put into a list of references for your paper or an email, or when instructors want to put links in SAKAI. This guide will give you information you can use to create persistent/durable URLs.


Proxy Prefix

A proxy prefix should be part of all library database URLs. This prefix allows students and faculty affiliated with the Claremont Colleges access to the databases regardless of their location on or off-campus.

Without the proxy prefix, users trying to access databases from off-campus will not be recognized as a Claremont Colleges user.

The prefix is:

Some proivders include the proxy prefix (e.g., ProQuest) but, in general, you will have to add this prefix to your URLs.
