On the 29th, the reporter learned from the Nanjing Library that Shen Xieyuan, an expert on the protection of ancient books in Jiangsu Province, the former deputy director of the ancient books department and research librarian of the Nanjing Library, died in Nanjing at 8:22 on March 29th, 2023, aged 100. Upon seeing this news, netizens have prayed in succession for this lovely old man, the "living dictionary of ancient books" in the library, to continue reading at the Paradise Library. Born in July 1924 in Suzhou, Shen Xieyuan was originally from Wuxi. He has successively worked in Shanghai United Public Library (now Shanghai Library), Wuxi Chinese Academy of Arts Library, Wuxi City Library, Beijing Chinese Opera Research Institute, Southern Jiangsu Revolutionary Cultural Relics Exhibition Hall, Southern Jiangsu Cultural Relics Management Committee, and other units. In 1955, he entered Nanjing Library to work until retirement. After retirement, he still devoted himself to the collation, research, and protection of ancient books. The Nanjing Library wrote in its obituary, "Mr. Wang devoted his whole life to the protection of ancient books and has had some influence in the field of ancient book edition research. In the 1970s and 1980s, Mr. Wang participated in the" Bibliography of Rare Chinese Ancient Books " In 1995, he won the "Outstanding Contribution Award" jointly awarded by the Ministry of Culture and the National Planning Group for the Arrangement and Publication of Ancient Books. He has been employed as an academic consultant in several domestic projects for the collation and publication of ancient books, and has served as an advisor to the Jiangsu Committee of Experts on the Protection of Ancient Books. In recent decades, Mr. Liu has been working tirelessly, focusing on the collation of postscripts and poetry collections by Huang Pilie, a famous Qing Dynasty book collector and collation expert. He is the author of "Collected Works of Shen Xieyuan". "Before his death, he basically completed the compilation of the Preface to the Scholar's Ritual Residence, which unexpectedly became an academic masterpiece." "This morning, Shen Lao walked very peacefully. When he woke up before leaving, the only thing he had in mind was the" Preface to the Scholar's Ritual Residence ", which had been brewing for more than ten years and had not been officially published." Ding Mingjiang, Shen Xieyuan's forgetful friend, told reporters, "The completion of the writing and editing of this book is also the main reason why Mr. Shen has lived a 'two front line' life at home and library in Nanjing for so many years." "After Shen Lao became famous for his news reports last year, many young 'forgetful friends' came to him for advice. During our stay in the hospital, every time we' forgetful friends' went to see him, the elderly were particularly happy, holding our hands and urging 'young people must read, read good books, and be good at reading'. The old man's voice, smile, and words were all vivid and unforgettable," Ding Mingjiang said. Li Jun, from the Ancient Books Department of the Suzhou Museum, was entrusted by Shen Xieyuan more than a decade ago to collate the electronic manuscript of Huang Pilie, a Qing Dynasty library collector, of the "Preface to the Imperial Residence of Scholars". "In those days, Shen Lao entrusted me to help him compile the handwritten notes of the Preface to the Scholar's Ritual Residence into an electronic manuscript for publication by the publishing house. Unexpectedly, these 800000 word notes have been collated for more than ten years. Shen Lao and I have collated and re collated them over and over again by letter and phone, and now this book has entered the final collation work." "Before Shen Lao died, I had a video call with him, and in the video, Shen Lao once again talked to me about the proofreading of this book. I promised him that I would help him see the publication of the" Preface to the Scholar's Residence "anyway," Li Jun told reporters. In the spring of 2022, Shen Xieyuan was accepting
