《旧唐书·列传·卷十五》
于是责成全国族谱书籍，根据史书记载考核它的真假，忠诚贤良的予以表彰提拔，违乱忤逆的予以批评废除，编写成《氏族志》。
于是普责天下谱谍，仍凭据史传，考其真伪，忠贤者褒进，悖逆者贬黜，撰为《氏族志》。
Therefore, the family tree books across the country were checked for authenticity by referenced historical records. The loyal and virtuous were commended and promoted, while those who violated the rules were criticized and abolished. This was compiled into "Clan Chronicles."
