New, Enhanced Interlibrary Loan Service: Article Express

Article Express is an 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 service is available for currently affiliated users at the West Lafayette campus.

Finding Article Express Request Options: Library Search and more

If using Libraries-subscribed databases for your research (e.g., Scopus), clicking the "Find it @Purdue Libraries" button will open Library Search and present you with multiple request options, including Article Express.

find it @purdue libraries example

If using Library Search for your research, always choose the "Everything" or "Search all" menu options.


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

Requesting articles through Article Express

Click the Request this article via Article Express link in Library Search to begin your request. The Article Express system will attempt to locate an open access (OA) version of the article first (an intermediary screen will provide instructions if you do not wish to use the OA version found). If no OA version is found, you will be taken to the following screen where you will be asked to enter your PURDUE email address. Submitting a non-Purdue email address will lead to a rejected request.

Click Request PDF to submit your request.

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. Short video example
