New, Enhanced Interlibrary Loan Service: Article Express

Article Express is a new, enhanced Interlibrary Loan service that provides almost immediate (within 2 hours) email delivery of articles from eligible journal content that you can request straight from Library Search. Eligible journal content currently includes all non-subscribed Elsevier journal titles and a few non-subscribed journal titles from other publishers (e.g. Mary Ann Liebert and Nature). Each PDF requested through Article Express will be paid for by the Libraries at an average cost of $25 per article. This new service is available for currently employed faculty/staff/visiting scholars and currently enrolled graduate students at the West Lafayette campus.

Frequently Asked Questions

What happens if I click Request this article via Article Express on an article that isn't included in the service?

Article Express knows what's eligible and what isn't, so it will redirect your request to traditional Interlibrary Loan (ILL) where we will attempt to obtain the article from another library. The ILL request from will be pre-filled for you and all you have to do is click submit. Short video example:

DOI/PMID Searching

If you conduct most of your research outside of our online catalog (Library Search), you may find the LibKey Nomad browser extension useful. LibKey Nomad is a browser extension that simplifies and streamlines access to the Purdue Library's subscription resources. Adding this extension to your browser enables one-click access to full text of articles from publisher pages, PubMed, Google, Wikipedia, and more, with no need to start at the library website. If direct access is not available, it directs you to our Interlibrary Loan request form or Article Express. To see the Article Express option, you must sign into Library Search with your Career Account/BoilerKey. Short video example

You may also find this DOI/PMID search useful. Direct link for DOI/PMID search.

Finding Article Express Request Options: Library Search and more

find it @purdue libraries example

If using Library Search for your research, always choose the "Everything" or "Search all" menu options. Also, make sure to check the "Expand search" box in the results list so articles with no-full text are shown. Short video example of keyword search:

If searching for articles outside Libraries resources (via the journal's website, for example), simply copy/paste the article title into Library Search, making sure to use the same recommended strategies above. We also recommend adding quotation marks around the title. Short video example:

You will only see this How to Get It option if you are signed into your Library Search account. Use the Sign In links presented to you on the article record page. You will remain signed in to your account throughout your browser session.


Requesting articles through Article Express
