魏晋南北朝时期,著名目录学家、时任秘书监丞的王俭,在编制官修目录《元徽元年四部书目》时看到四分体例在反映当时图书发展情况时的不足,又深深体会官修目录的弊端,继承刘歆《七略》的优良传统,以七分法著录图书,编成《七志》。开创了私家目录的先河,掀起了一股书目分类体系回归“七分”的潮流。 During the Wei, Jin, Southern and Northern Dynasties, Wang Jian, a famous bibliographer and then secretary of the Central Government, saw the inadequacies in reflecting the development of the books at the time when compiling the official catalog “Four Bibliographies of the Yuan emblem” To understand the shortcomings of official catalogs, to inherit the fine tradition of Liu Xin’s “Seven Loots,” to record books in a seven-point scale, and to compile “Seven Chronicles.” Creating a precedent for private directory, set off a bibliographic classification system regression “seven points ” trend.
