ScienceDirect is a website operated by the Anglo-Dutch publisher Elsevier. It was launched in March 1997. It is a platform for access to nearly 2,500 academic journals and over 26,000 e-books. The journals are grouped into four main sections: Physical Sciences and Engineering, Life Sciences, Health Sciences, and Social Sciences and Humanities. For most articles abstracts are freely available; access to the full text (in PDF and, for newer publications, also HTML) generally requires a subscription or pay-per-view purchase.
