Members are largely divided into institutional membership and individual membership as follows.

Institutional membership

An institutional membership is a member of an organization that has contracted a paid content service with a company from an organization such as a university, a research institute, and so on. Content that is contracted on a PC or other device within the organization's IP band is available.

Individual membership

Individuals can subscribe to paid content services with their company, sign in with their ID, and use the contracted paid content.
