《论衡·卷十三·别通篇》
兰台令史虽然地位低微，却掌管着国家的珍贵图书资料，通人就由此进身做官，像博士这样的官，儒生就是由这里开始做起的。
令史虽微，典国道藏，通人所由进，犹博士之官，儒生所由兴也。
Although the records editors in Lantai are humble, they are in charge of the precious books and documents of the country. Scholars enter the officialdom from here, and Confucian scholars begin their careers from the position of doctor.
