徐世昌在中国近代史上的地位可谓举足轻重。1886年进士及第后，他历任翰林院编修、新建陆军参谋营务处总办、商部左丞、巡警部尚书、军机大臣、东三省总督、邮传部任尚书等，进入民国后又因曾担任民国总统而叱咤政坛、显赫一时。徐世昌平日喜好读书、写诗、作画，还主持编纂了多部书籍，对典藏书籍也满怀热情。庚子之前已有一定藏书，不幸在此次战乱中毁弃。自1914年后，他在充足财力的支持以及门客僚友的协助下，积十余年之力而收聚起七千余种书籍，规模甚为可观，逐渐成为民国有名的大藏书家。所藏存储于北京东四五条胡同寓处，藏书楼名为书髓楼。1922年徐世昌下台退居天津后，在天津也逐渐积累起部分藏书,北京藏书仍存于原处，设专人看管整理。徐世昌藏有近十余种宋元本,大多为明清本。史部中所收地理类书籍较多，且所搜集的名家旧藏也不少。其藏书最大特色在于收藏集部尤其是清人诗文集数量最多，其中写本、抄本、稿本等罕见本较多。徐世昌对所藏之书十分爱惜，新购进之书会托人为其装裱并加盖其藏书印。并自1915年就曾嘱托旧友贺涛之子贺葆真为其藏书编订书目，此即1935年刊行的《书髓楼藏书目》。本文共分三章。第一章为徐世昌研究。主要对徐世昌的家世、生平做了叙述，介绍了与其在文化、藏书方面交往密切的几位友人，并对徐世昌主持编纂的主要书籍在内容上做了大致的描述。第二章为徐世昌的藏书研究，共分六部分，首先介绍了徐世昌藏书的缘起及规模，接着探讨了徐世昌聚书的途径、分析了徐世昌藏书的特点、考察了他对藏书的利用和流通、梳理了其藏书的流散去向，并在此基础上总结出徐世昌藏书对当代公共藏书的几点借鉴和启示。第三章为藏书目录研究。先是对此藏书目的作者贺葆真做了详细介绍，然后对比和考证了《书髓楼藏书目》以及《晚晴簃所藏清人别集目录》这两个同为徐世昌藏书目的关系，最后重点分析了《书髓楼藏书目》在编写上的特点以及它的价值和不足。总的说来，徐世昌在藏书上取得如此大成就，与当时的时代背景、友人的协助以及有力的政治地位是分不开的。作为民国私人藏书家，徐世昌的藏书对在战乱时期保存中华文化典籍、传承中华传统文化做出了重大贡献，他在藏书中所表现出的谨慎态度、执著精神以及对书籍的爱护之情等都值得当代藏书机构学习和借鉴。

Xu Shichang played an important role in china’s modern history. He became an Imperial Scholar when in 1886, and he once served as a new army camp staff, business office agent ZuoCheng, Patrol government minister, Military minister, the Northeast Governor, and Postal Department chancerymail and so on in Qing Dynasty. After entering the republic of China, He was well-known as the president at that time. Xu Shichang preferred to reading, writing and painting in his spare time. What's more, he was also enthusiastic about collecting books. Before 1900, he had collected many books. Unfortunately, they had been destroyed in the war. Since 1914, with sufficient financial resources and his friends’ help, he gathered up more than seven thousand kinds of books, and gradually became a famous book-collector in the republic of China. These books were stored in Beijing residence. In 1922, Xu Shichang left Beijing for Tianjin,he also collected many books there. Someone was respectively sent to take care of his books in Beijing and Tianjin. Xu Shichang had nearly more than 10 kinds of books which were Song and Yuan version, but most of them were the Ming and Qing version. In Shi Bu, geographic books accounted for a large proportion.besides, he collected many books which were once in the hands of famous book collcters. The biggest characteristic of Xu Shichang’s book collction is that he collected JiBu largest, especially collection of Potems in the Qing Dynasty. In these books we can find versions of writing, manuscripts and so on. Xu Shichang cherished his books; newly purchased books were always framed and stamped with his seal. Moreover, he also entrusted He Baozhen, his close friend’s son, to compile a bibliography for his books, this is the Book Catalogue of Shu Sui Lou, published in 1935.This article is divided into three chapters. The first chapter is the study on Xu Shichang. It mainly introduces Xu Shichang’s family, his whole life and his several close friends with who he contacted frequently in culture and book collection. In addition, I also give a rough description of books which were compiled by him.Chapter ii for Xu Shichang’s book collection research is divided into six sections. It refers to a series of questions, such as the origin and scale of his book collection, the way he collected books, the characteristics of his books, as well as the books in use and circulation. Besides, I investigate where his books vanished after he died, and summed up some reference and enlightenment on contemporary collection organization. The third chapter researches to the Book Catalogue of Shu Sui Lou. Firstly, I introduce He Baozhen in detail, who is the editor of the the Book Catalogue of Shu Sui Lou. Then I discuss their relationship between the Book Catalogue of Shu Sui Lou and the book catalogue of Qing Dynasty collected works in Wan Qing Yi on the basis of comparison. In the end I focus on analyzing the Book Catalogue of Shu Sui Lou’s characteristics in compiling as well as its value and inadequacy. Overall, Xu Shichang made such great achievements in book collection, I think the background of that time, friends’ help, and powerful political power is the indispensable factors. As a private book-collector in Republic of China, Xu Shichang's collection could contribute to preservating Chinese cultural classics, and inheriting Chinese traditional culture. His cautious attitude, dedication and love of books are worthy of study.
