1997年前广东省18个出版社（公司）只有16个出版社向广东省中山图书馆缴送了样书。除广东科技出版社每种缴送两册外，其余15个出版社均只缴送单本。1997年，我们抓住这个机会向从未向我馆寄送样书的广东世界图书出版公司和珠海出版社发出信函，要求他们按粤宣通［1997］6号文的 Before 1997, only 18 publishing houses of 18 publishing houses in Guangdong Province (companies) paid a sample book to Zhongshan Library of Guangdong Province. In addition to Guangdong Science and Technology Publishing House for each payment of two volumes, the remaining 15 publishers only pay a single. In 1997, we seized this opportunity to send a letter to Guangdong World Book and Publishing Company and Zhuhai Publishing House, who have never sent samples to our museum, asking them to press Guangdong Xuan Tong [1997] No. 6
