采用CiteSpace知识可视化工具，基于关键词共现分析法、膨胀词探测法和内容分析法，重点对PQDD数据库中3973篇欧美图书馆学博士论文的研究热点进行分析，此外，还探讨研究热点的演化、研究前沿及其演化。总体上，欧美图书馆学博士学位论文研究主题特征表现在：研究内容偏重应用，绝大多数论文面向具体图书馆服务与管理，以及以解决实际问题为目标的工作实践。这与欧美整体科学研究的实用性和实证性价值取向是一致的。此外，研究主题多样和细致，非常注重具有特殊身份和职业特征的小用户群体和图书馆馆员研究。图4。表3。参考文献23。

Europe and the United States are considered to be the leaders in the field of library science research. Their doctoral dissertations have an irreplaceable role for studying and tracking the development of library science. In this study, 3 973 doctoral dissertations in the database of PQDD from year 1925 to 2013 are used as the research object. Keywords co-occurrence analysis and expansion word detection methods embedded in CiteSpace are used to generate knowledge map on the theme of the research topic. Knowledge map is used to obtain the clues of the theme and to analyze the content in-depth in order to reveal the research focus, frontiers and their evolution in a period of 89 years. Six features of research themes are displayed. 1） History inspection in specific libraries has been concen- trated in the studies of all kinds of libraries, especially in the studies of public libraries and academic libraries. Compared with public library researches, academic library pays more attention to the strategic development and at the same time to the detailed problems specific to this kind of libraries. 2） Research innovations in information retrieval and information behavior are significant in the interdisciplinary research and the main research bodies are computer technology, mathematics and sociology; the objects of the study focus on specific professions and small user groups with special background. 3） Research on practical guidance of information literacy is active. Not only the information technology is used in the information literacy education, but also the construction of curriculum system and the development of evaluation index system are used; at the same time, the influencing factors of information literacy of different personality traits has also got full attention. 4） Librarians in the research of library management are the most remarkable topic. In research topics of library management based on human resource management, librarian study accounted for over sixty percent of the total, both for the analysis of characteristics of the librarians themselves and the analysis of librarians＇ work satisfaction. At the same time, librarians＇ professional development, librarians＇ identity, librarians＇ ability and education research are also some of the hot topics. 5） The research problems of digital library are very precise although the amount is not rich. Researchers chose technology application and development and usability as the main bodies. Meanwhile, some papers pay attention to factors other than technologies, such as society, psychology, economy, and politics and so on. 6） The orientation of the research about information service is clear. Some researches aim at information service and influencing factors of different users, and some researches emphasize on service practice of various subjects. Since 2015, research fronts are evolved gradually. With the continuous influence of technology and education innovation, the view of library research is becoming more and more open. The research domain will be expanded and extended. The research fronts will evolve along the cross-synthesis of subjects of library and information science, computer and information science, communication and journalism, education science, management science. User＇s demand is considered as the basic point, management and service revolution as the method. This study carried out a data analysis of a time span up to 89 years and chose knowledge map analysis method as the clues to obtain research topic and used content analysis method to analyze subjects and to en- sure the objectivity of theme analysis and accuracy. Compared with the existing research, it may improve the comprehensiveness and accuracy of the data and reflect the characteristics of the evolution of research topics objectively. The results would be more specific if literature co-citation methods were combined to do the research. 4 figs. 3 tabs. 23 refs.
