近几年,千家驹先生主编的《中国钱币大辞典》指定由我撰写两宋词条。通过一段实践,我体会到,既要对前人发现的稀见宋钱品种,运用史料,再进行思考和辨析,又要随时注意新的信息资料,二者必须兼顾。撰写词条同时也是不断学习和提高的过程。今先例举三条,谈谈个人浅见,尚祈读者指教。 In recent years, Mr. Qian Jiaju’s “Dictionary of Chinese coins” designated by me to write the two Song entries. Through a period of practice, I realized that it is necessary to take into account the rare Song Dynasty money varieties discovered by our predecessors, make use of historical materials, think and discriminate again, and pay attention to new information materials at any time. Both of them must be taken into consideration. Writing entries is also a continuous process of learning and improvement. This precedent cited three articles, to talk about personal humble opinion, still pray for readers.
