Using Electronic Resources

Browser extensions can efficiently connect you to the full text of publications, bypassing the need for PennText pages. Try them all to see which ones fit best with your workflow. Keep them all or just those that work for you.

Why use browser extensions?

  • help quickly connect you to PDFs
  • allow bypass of PennText pages
  • some give options for ordering article if the full text is not found online

What do browser extensions do?

  • Scan the page metadata for DOIs (digital object identifiers) and sometime PubMed PMIDs (unique identifiers used in the PubMed database)
  • Search library holdings and open access journals (often using unpaywall database of open access articles)
  • In the case of the Google Scholar button, search Google Scholar, Researchgate and authors' personal websites (questionable copyright) for the title
  • some give options for ordering articles if the full text is not found online

Browser extension compatibilities

Extensions generally work best with the most updated versions of modern browsers.
