UT Libraries’ licensing agreements restrict access to certain academic journals and online sources to current faculty, staff and students. It is a copyright violation to share PDF copies from publishers who have not made those articles openly available.
If you have trouble accessing a citation, check to see if any free/open access copies of the exist by using tools such as the Unpaywall extension for Firefox and Chrome, Open Access Button, Tennessee Electronic Library (or other free virtual library based in your state), Google Scholar or TRACE. Your public library or other affiliated library/institution may be able to access an article free of charge or at minimal cost through an interlibrary loan program.
