1science, acquired by Elsevier in 2018, was created to expand the scope of existing abstracting and analytics databases. It aims to include quality controlled academic and research documents in all disciplines and languages and from all countries. Its core index, 1findr, currently comprises more than 120 million metadata records, including over 30 million links to free full-text articles selected from about 100,000 referred scholarly journals.
