When browsing the Internet :

  • whatever the site (Google, Google Scholar, publisher sites, Wikipedia...)
  • whatever the query (article title, authors, DOI...)
  • the Click & Read extension scans the web page you are visiting page you are visiting, looking only for document identifiers DOI, PMID, PII (Elsevier identifier)
  • then searches for the document that corresponds to the identifier found in the the configured document collections
  • and adds the C&R button if the resource is available

Just click on the button to access the document.
