For a century, the Hein Company has catered to the library community—first law libraries, and now academic, high school, government, corporate, and public libraries as well. Catering, to us, means recognizing the needs of the librarian and responding in a thorough and timely manner. As we’ve listened to various library communities over the years, we’ve established several account features and services for our HeinOnline customers. Learn more about them below.

Digital Services
