In accordance with the change of time and circumstances, the structure type of library also changes ceaselessly. It has transformed from paper library into the co-existance sitution of paper & electronic media library and then further into the electronic library age Accordingly, the reciprocal relationship between librarians and libraries has also changed, from "besonderes Gewltverhaltnis" into "Human right protection", and further being revised into "allgemeines Gewaltverhaltnis". In short, the interior relationship in librarianship will advance as the times instead of remaining motionlessly in the past, at present or in the future.
