Profile match
RELX is a British information and analytics group formed in 1993 through the merger of Reed International and the Dutch publisher Elsevier, and it has since converted a print publishing business into a subscription data company. It operates four divisions: Elsevier in scientific and medical research, risk analytics covering insurance and financial crime screening, legal information through LexisNexis, and the exhibitions business RX. Headquartered in London and listed in London, Amsterdam and New York, it derives the large majority of revenue from electronic products and analytics rather than print.
