However, the reality is that many students are at a loss in the face of the sudden free environment after entering the university, and over time they have formed the concept of "playing for a few years". This paper will talk about college students' autonomous learning from three aspects: the importance of the library, the distribution of library collections and how to use the library. First, the status of the library The library is a temple of culture and an ocean of knowledge. A national library collects not only books, but also the soul and spirit of a nation. Some philosophers say that the most effective and quickest way to destroy a country is to burn down its library. 1933, after Hitler seized the German regime, he ordered a large-scale book burning. In order to remember this painful historical lesson, a floor-to-ceiling window has been opened in the square of the National Library in the center of Berlin with bulletproof glass. After Qin Shihuang unified China, in order to unify his thoughts, he also burned books and buried Confucianism on a large scale. Books are the carriers of human knowledge and thoughts. Burning books and libraries is tantamount to clearing culture and cleaning the brain. It is also said that it doesn't matter whether a university is famous or not. What matters is how many books there are in its library and how many old professors with white hair are on campus. If a school library is rich in books, enough for you to read and absorb in the university, then even if you are unknown, you can become a knowledgeable person through self-study. The importance of university library to a university means the importance of national library to a country and a nation. Teachers should go to the library to collect information when studying and researching topics, and students should also go to the library to obtain resources for self-study and homework. All excellent universities will put the library in the center of the campus when designing the campus to reflect its important position. Personnel working in the library will also be strictly selected. II. Distribution of Library Collection The library is the document information center of a school and an academic institution that provides services for teaching and scientific research. The collection construction of the library is closely related to the discipline setting, teaching and scientific research direction of the school, and the literature collection focuses on the basic theoretical literature, teaching reference literature and scientific research reference literature of the disciplines involved in various majors of the school. For example, the collection construction of Guangsha College Library takes into account the discipline setting and professional characteristics of the school, and the collection is mainly architecture, English, logistics and international trade; As for the majors that are not set up in the school, such as medicine and music, there are few related books. Besides paper books, there are e-books in the library. E-books have many formats, such as CEB, PDF, HTML, TXT and OEB. Different e-books need different readers: EXE files do not support Flash and Java as well as common audio and video files, and need IE browser support; PDF file format is an electronic reading file format developed by Adobe company in the United States, and its electronic reading needs AdobeAcrobatReader, the company's PDF file reader, to read. University libraries are mostly divided into circulation department, editorial department, electronic reading room, information center and system maintenance department. The circulation department is the place where students go most. The circulation department is generally divided into liberal arts stacks and science stacks. Libraries with large buildings and rich collections will further subdivide liberal arts stacks and science stacks. For example, social science is put in a separate room, literature and language are put in a room, computers are put in an outdoor room, and architecture is put in a room. There is a collection map in the library hall, so readers can browse it before borrowing books, so as to borrow them in a targeted way. Books are generally divided into 22 categories: (1) Marxism-Leninism, Mao Zedong Thought and Deng Xiaoping Theory; (2) Philosophy and religion; (3) Introduction to social science; (4) politics and law; (5) military; (6) economy; (7) Culture, science, education and sports; (8) language and writing; (9) literature; (10) art; (1 1) historical geography; (12) natural science; (13) Mathematical Science and Chemistry; (14) astronomy and earth science; (15) biological science; (16) medical and health; (17) agricultural science; (18) industrial technology; (19) transportation; (20) aviation and aerospace; (2 1) environmental science and safety science; (22) comprehensive books.
