"Authorized
Users" are authenticated, current, full- and part-time students,
employees (including faculty, staff, affiliated researchers, independent
contractors, and walk-in users), and other individuals who have legal
access to the Subscriber's facilities and computer network. Remote access
is allowable to Authorized Users only if they are authenticated through
a secure network. Open proxies and other nonauthenticated proxy servers
are prohibited.
An "Institution" is all parts of an organization that report to the same Chief Academic Officer or Chief Executive Officer. For multicampus academic institutions, each organization listed in the Directory of Higher Education is a separate Institution (http://www.educause.edu), and requires its own Site License. For the purposes of these terms and conditions, academic law libraries and academic medical libraries are considered part of a university and are part of an Institution only if they report to the same institutional Chief Academic Officer. |
