Journal titles are searchable through the Penn Libraries' catalog, Franklin. Combine keywords and filter results by 'Journals/Periodical' to browse available journal titles.
Articles are independently searchable through Articles+, the Penn Libraries' entry point to ebooks, scholarly journals, newspaper articles, and conference proceedings.
If you discover an article Penn Libraries' currently doesn't provide access to, if you fill out an article request form you should be able to receive the article within 3-5 days (but often much quicker) via resource sharing.
Look for the Penn text icon, "full text online", "citation online" links to connect with articles or to request digital scans
