Elsevier is a Dutch publishing and analytics company specializing in scientific, technical, and medical content. It is a part of the RELX Group, known until 2015 as Reed Elsevier.
Its products include journals such as The Lancet and Cell, the ScienceDirect collection of electronic journals, the Trends and Current Opinion series of journals, the online citation database Scopus, and the ClinicalKey search engine for clinicians.
Elsevier's products also include digital tools for data management, instruction, and assessment. Elsevier publishes more than 470,000 articles annually in 2,500 journals. Its archives contain over 16 million documents and 30,000 e-books. Total yearly downloads amount to more than 1 billion.
Elsevier's high operating profit margins (37% in 2018) and 950 million pounds in profits, often on publicly funded research works and its copyright practices have subjected it to criticism by researchers. Elsevier is the world's largest publisher of academic articles.
It publishes 420,000 articles a year in about 2,500 journals. Its best-known titles are The Lancet and Cell. In 1995, Forbes magazine (wrongly) predicted Elsevier would be "the first victim of the internet" as it was disrupted and disintermediated by the World Wide Web.
