Elsevier

Elsevier ( ) is a Dutch academic publishing company specializing in scientific, technical, and medical content. Its products include journals such as The Lancet, Cell, the ScienceDirect collection of electronic journals, Trends, the Current Opinion series, the online citation database Scopus, the SciVal tool for measuring research performance, the ClinicalKey search engine for clinicians, and the ClinicalPath evidence-based cancer care service. Elsevier's products and services include digital tools for data management, instruction, research analytics, and assessment. Elsevier is part of the RELX Group, known until 2015 as Reed Elsevier, a publicly traded company. According to RELX reports, in 2022 Elsevier published more than 600,000 articles annually in over 2,800 journals. As of 2018, its archives contained over 17 million documents and 40,000 e-books, with over one billion annual downloads.

Researchers have criticized Elsevier for its high profit margins and copyright practices. The company had a reported profit before tax of £2.295 billion with an adjusted operating margin of 33.1% in 2023. Much of the research that Elsevier publishes is publicly funded; its high costs have led to accusations of rent-seeking, boycotts against the company, and the rise of alternate avenues for academic publication and access, such as preprint servers and shadow libraries.
