Google Scholar allows you to search for primarily scholarly or academic articles. It pulls from various sources, including open access (freely available) online journals, journal publishers, and institutional repositories (where faculty, staff, and students can place their academic work online). However, some content is behind a paywall.
While you're a student at LSU, you can search the Libraries to see if we have the full-text (if we don't have it, we can get it for you - no cost).
