The difference between library science, philology, information science, archival science and bibliography is incisive.

Library science, which originated from Wuchang Wenhua School in the 1920s and 1930s, is now in the School of Information Management. Ms. Wei Dihua introduced China from the United States. The traditional China library school is a library-style literature collection, such as Tianyi Pavilion. Modern library science is a subject that studies library service and library management, including library business process, library technology, library management, library service, digital library, information service, document service, library alliance and so on.

Philology, biased towards history. Including bibliographic documents, local documents, historical documents, etc. Bibliographic literature and local literature are also one of the research contents of library science. Historical documents emphasize history.

Information science, which traditionally originated from military and literature, has now extended to the commercial field. Including military information, library information (more combined with library science) and business information (more combined with business disciplines). After the founding of People's Republic of China (PRC), in the 1950s, China set up scientific and technological information research institutes in various places to provide information services for China's science and technology and industry, including tracking, translating, analyzing and extracting foreign documents, so as to improve and support domestic technology. In the 1980s, the United States established SCIP (Association of Competitive Intelligence Practitioners), which brought intelligence into the commercial field (in fact, after World War II, Japan began to spy and collect intelligence all over the world, forming a strong intelligence conversion rate), and the world began to pay attention to the actual combat of competitive intelligence in business. In China, in the late 1980s and early 1990s, some experts and scholars who switched from scientific and technological information to commercial information, such as Mr. Bao Changhuo, began to introduce competitive intelligence into China. From the end of 1990s to the beginning of 20th century, China gradually paid attention to the competitive intelligence research and actual combat in the fields of enterprise strategy, intelligence collection, intelligence analysis, intelligence transmission and anti-competitive intelligence. Around 20 10, China's competitive intelligence is gradually systematized. However, due to the different domestic environment, China's competitive intelligence is more theoretical than practical. With the participation of more and more business talents, there will be more and more practical competitive intelligence in the future. Thus, information science is a series of disciplines that study information collection, analysis, transmission and feedback. Today's information science includes a series of directions, such as library information, military information, business information, information analysis, information system, data mining, information service, information early warning and so on. Personal preference information science.

Archival science studies a series of disciplines such as the collection, arrangement, identification, preservation, evaluation and utilization of archives. The key of archival science lies in archives management, which is more complicated. At the same time, there are many standards and operating procedures for the collection of archives, and many conditions are needed for the preservation of archives. Archival science is boring, but it needs more attention. Archival jobs are essential in large state-owned enterprises, and the employment rate is not bad.

Bibliography, some library science and philology. Studying the general law of the formation and development of cataloging work, that is, the science of studying the movement law of bibliographic information, is a theoretical summary and summary of the practical experience of cataloging work. There is not much research in this field.

Generally speaking, the scope of information science is the widest, followed by library, followed by philology, bibliography is narrow, and archival science is more professional. At the same time, in the big discipline environment, library science and information science are relatively close, and archival science is also relatively close to these two. Library, information and archival science is the first-class discipline of the whole country.
