Paper Keywords: Librarian's ability Abstract: This paper mainly discusses that in the era of knowledge economy, librarians should have the ability of lifelong learning, various practical abilities and strong psychological adaptability, so that the library can better play the role of information resources service. The era of knowledge economy has produced a series of new information, communication means and cognitive tools, which have had a profound impact on education. The emergence of knowledge economy puts forward new requirements for university library education, which makes university library education face new challenges. Therefore, under the condition of knowledge economy, studying the educational reform of university libraries and strengthening the cultivation of the quality and ability of university librarians will certainly play a great role in promoting the realization of China's new economic development strategy. We believe that in order to better meet the new challenges, librarians must have the following basic abilities. 1 the ability of lifelong learning 2 1 century is a learning society, and learning to learn has become the theme of education reform in the new century. Today, in the era of knowledge economy, with the rapid development of science and technology, high-tech products with higher and higher scientific and technological content are constantly emerging. The constant changes of social structure and talent market put forward new requirements for the quality of workers. The era of one-time school "charging" and lifelong work "discharging" has become history, leading to lifelong learning. This requires librarians to master scientific learning methods and form learning ability. Learning ability is a comprehensive ability, which includes three basic functions: first, the ability to acquire knowledge, including the ability to read blasphemy, listen to memory and collect information; The second is the ability to consolidate knowledge, including the ability to consciously remember, selectively store knowledge and accurately reproduce knowledge; The third is the ability to apply knowledge, including the ability to express, operate, analyze and solve problems. Most of our librarians are trained under the original education system, and there is a general problem of narrow professional caliber. For librarians who undertake the mission of spreading human civilization, only by constantly learning and striving to improve their humanistic and scientific literacy, can they be competent for the historical mission entrusted to us by quality education, so as to have a broad knowledge base and rich cultural background, and be good at judging, selecting and organizing all kinds of new information. 2 Various Practical Abilities In quality education, university librarians must have the following practical abilities in order to be fully competent in teaching and educating people. Language expression ability. As a way of working, the main feature of librarian's work is to complete the task through the understanding and expression of language. Therefore, whether the understanding of language is correct, whether the expression is standardized, clear, concise, vivid, humorous and humorous, and whether it is logical is directly related to the effect of library education. Educational research ability and the ability to use advanced educational means. Ability to master modern management technology. The rapid development of modern science and technology provides a series of advanced management technologies for the modern management of libraries. In order to achieve good results in library education, librarians must strengthen the study and research of modern technology theory and enrich themselves with modern management technology theory. Librarians must learn to use these advanced management methods and modern technologies. Ability to access information. As an important position for spreading cultural knowledge, the library should effectively develop and utilize information resources to realize the real value of information. This requires librarians to have keen information consciousness and information quality, and master the ability of obtaining information, updating, spreading, developing and utilizing information. Have a certain level of foreign language ability. The important symbol of library modernization is computer management. To make good use of computers and develop and utilize information resources on the Internet, we must have a certain level of foreign languages, so as to track and capture modern development information on the information network in time, sort out and develop information resources, and improve the utilization rate of network information resources. Ability to analyze and solve practical problems. University librarians, as knowledge disseminators, cannot be competent for library education without solid theoretical foundation and profound knowledge. However, if you only have book knowledge and lack practical work experience and training in application, operability and skills, it is difficult to complete the task smoothly. Therefore, university librarians should actively participate in social investigation and practice, and strive to improve their ability to analyze and solve practical problems by using the theoretical knowledge they have learned. Interpersonal skills. Librarians are good at communicating with students and should try their best to create an atmosphere full of genuine concern. Secondly, librarians should be good at communicating with the practical departments and their staff in the society, and establish close ties, so as to create favorable conditions for strengthening the practical process in library education. Good psychological quality and strong psychological adaptability are important basic qualities of people. As the provider of educational services, the psychological quality of librarians directly affects the effect of library education. So, what psychological qualities should an excellent librarian have? The author believes that there are mainly the following aspects. A keen observation. Quick and accurate judgment. Librarians should have the ability to understand students' personality characteristics and be good at understanding students' interests, aspirations, needs, motivations, emotions and ideas, so as to continuously improve their work. Good at making emotional reactions. As a member of society, librarians also have human nature and emotion. Through straightforward and reasonable emotional expression, teachers and students can get to know each other and get along sincerely. However, the professional characteristics also require that the librarian's emotional tone in front of students must be cordial, enthusiastic, relaxed, happy, stable and self-controlled, and he should not be moody, cold and hot, which makes students puzzled; Library education must eliminate bad emotions. Only in this way can students have a warm and happy emotional experience, and thus take the initiative to accept the education of the library with a positive attitude. A just attitude. Librarians should not be unfair to please individual students, but should treat all students equally. If the librarian is partial to students, on the one hand, it will promote some bad qualities of the biased students to grow secretly, on the other hand, it may promote some good qualities of the unbiased students to disappear invisibly without being strengthened. Positive emotions and strong will. With the deepening of educational reform, librarians themselves will face competition and challenges, and may even have a crisis. Therefore, we must have the confidence and courage to meet the challenge and the strong will to overcome the crisis. The road of life cannot be smooth sailing, and setbacks are inevitable. It is important to have the ability of psychological adjustment, and not to be dejected and depressed in adversity; Don't be arrogant and don't be carried away by prosperity. Magnanimous measurement. A qualified librarian must treat different opinions from peers and students with a normal heart and have a broad mind. When dealing with daily interpersonal relationships, we should strive to be lenient with others, be strict with ourselves, and unite with comrades widely, including those who have opposite academic views and those who have opinions about themselves at work; Be willing to recommend talents and help others. In short, in the era of knowledge economy, librarians should constantly enrich and improve themselves, constantly improve their comprehensive quality and ability, provide high-quality services to students in an all-round and multi-level way with solid professional knowledge and extensive knowledge of other disciplines, infect students with professionalism, responsibility and dedication, and make students improve their comprehensive quality in a subtle way, so that the library can adapt to the needs of modern social development and better play the role of the library.
