Elsevier serves the global research community to deliver open science

"More recently, we’ve taken big steps to support open science. We are one of the leading open access publishers, and we make more articles openly available than any other publisher. We make freely available open science products and services we have developed and acquired to enable scientists to collaborate, post their early findings, store their data and showcase their output. We make Mendeley — a reference manager and collaboration solution — freely available for the millions of researchers that use it while also adding free data search and storage services."
