Безопасен ли oclc.org?

From their site: "OCLC is a nonprofit, membership, computer library service and research organization dedicated to the public purposes of furthering access to the world’s information and reducing information costs. More than 72,000 libraries in 170 countries and territories around the world have used OCLC services to locate, acquire, catalog, lend and preserve library materials." My librarian friends think highly of them. Site seems entirely benign to me.
