Search the article title in Summon. If we have the full text it should be one of your top results. Access the PDF and you're done! No luck? Move on to step 2.
Search the article title in Google Scholar. If full text is available through Google Scholar it will be located in a link to the right of the citation. If not, move on to the next step.
Double check library access by using the Journals by Title search. If we have a subscription to the journal that covers the volume and issue needed you should be able to browse to the PDF. If not, proceed to the next and final step!
Prompt an Interlibary Loan request. In Google Scholar you can use the >> icon under the citation to locate the "Library Search" function. That should take you to a screen where you could submit an InterLibrary Loan request. You can also get to this screen through Summon (try adding the "results beyond your collection" filter to locate the citation) or by searching EBSCO. If need be you can also start an ILL request by scratch.
If you just need a single chapter of a book, consider skipping to step 4 and submitting an ILL request and we will scan the chapter and send it to you. To make sure you get a scan and not the entire book make sure you ILL request is set to copy not loan.
You might want to bump this step up to #2 if you are looking for an ebook.
It is almost always easier to submit an InterlibraryLoan request by finding a record for the item first. Worldcat is a global library catalog where you can find an entry for the book in question and use it to prompt an ILL request.
