The purpose of this study is to inquire about the trait of represented information self-organization in reader’s mind. From the viewpoint of complex network system, the represented information in reader’s mind is hold in the characteristic of complexity. The reader solves the problem of complexity through making network of information. The making information network is accomplished by information self-organization. The information self-organization reveals three aspect traits: the mechanisms, the attributes, and the characteristics. The mechanisms are contained four factors: deflection, interdependence, interaction, and feedback. The attributes are consist of four essential elements: systematic construction, optional selection, variableness shape and repetition activity. The characteristics are possessed four component parts: the arbitrary organization of information, the conditioning feedback, the reader’s intention participation, and the specification of emerged meaning. The reader emerges the meaning through linking represented information to network. The reading educators should perceive the trait of self-organization in networking represented information for meaning emergence.
