In today's personalized personality, personal digital libraries have quietly appeared in the library world, and there is a trend of gradual popularization. For example, in China People's Liberation Army Xi Political College, many teachers and students are building their own digital libraries. It has become a fashion to establish and own a personal digital library there. Professor Walter WANG of the Institute has more than 5,000 kinds of books in his personal digital library. According to his own teaching and research, he collected and sorted it through online downloading, scanning and burning. In the electronic reading room of the hospital, many students consult e-books online and copy the burned materials. They believe that it is convenient and quick to acquire the professional knowledge needed for personal study and scientific research and establish a personal digital library. It used to take at least ten and a half months to write a paper and consult relevant information. Now the digital library can be completed in a few minutes, with a wider coverage and more comprehensive reference content.
3 the concept of personal digital library
The so-called personal digital library means that individuals use free or basically free full-text database software on their own computers to collect and store relevant online information and self-created digital information resources, making it an organized information collection. Personal digital library is a type of digital library, which is closest to the personalized needs of users. In fact, the personal digital library is a private library in the E era.
Four Functions of Personal Digital Library
4. 1 information warehouse. Personal digital library is a personal information warehouse. You can grab and build at will, including words, pictures, animations and other elements, but these elements can be stored separately in the page or in the database. Personal digital library is based on personal computer. Once built, it has great independence, can not be affected by web page updates, dead links and broken links, can well retain the original web page, and can ensure the reliability of web page links. The information resources of personal digital library are resources that individuals have "obtained", so they are "real" and a kind of "real storage". In short, the personal digital library is a private "library building" in the E era, and individuals can grab the required information from the "collection" anytime and anywhere, thus giving full play to the function of the information warehouse.
4.2 Information control. The overwhelming information on the Internet makes people feel at a loss. If we can't make good use of it, it will not only waste resources, but also cause some information pollution. Therefore, individuals cannot simply use external information resources, but must choose and dominate information resources according to their own interests, hobbies, specialties and specialties. Personal digital library provides powerful information control function. As a collection of knowledge, personal digital library selects and controls the scope and depth of knowledge, optimizes the combination of collected knowledge elements, and specially customizes online information to help individuals master very practical knowledge.
4.3 Self-study weapons. In the climax of today's knowledge economy, lifelong learning and autonomous learning are no longer a slogan, but have become the real actions of the vast majority of people. Personal digital library is an effective weapon for individuals to study independently and carry out scientific research, and it is the closest learning method to individuals. In the process of constructing personal digital library, it is also a process of personal synchronous learning. After the establishment of personal digital library, individuals can freely choose information resources suitable for them and learn at their own pace. At the same time, individuals can also independently control the learning scene and dynamically control the information resources.
5 the necessity of establishing a personal digital library
5.1the call of the times. Historically, a large number of private libraries have played an important role in preserving cultural classics, spreading culture and assisting in cultivating talents. Bibliometrics statistics also show that among the documents cited by authors, the citation rate of personal books is often the highest. Based on the E-era network environment, people can download all kinds of information related to their work, life and research from the Internet. However, with the accumulation and download of information, effective management is objectively needed. Personal digital library is a tool to collect and manage personal digital information.
5.2 Demand for personalized service. Personal digital library has realized the real personalized service. At present, the online resources are too complicated and the content quality is uneven, so users often feel at a loss and at a loss. Many Internet information resources retrieval tools, including public digital libraries, provide a relatively extensive and extensive tool. In principle, all kinds of personalized services it provides are mainly based on mechanical matching, which can only be said to be in the primary stage of personalized services and difficult to meet the real needs of individuals. Personal digital library completely returns the freedom of choosing information, creating knowledge and organizing knowledge to individuals, and realizes complete "personal manufacturing". Therefore, it is an effective way to provide truly personalized service.
5.3 Supplement to public digital library. Compared with public digital libraries, personal digital libraries have many unique advantages. It collects a lot of personal data, many of which are not available in public digital libraries. For example: some personal works, e-mail files, photo albums, address books, worksheets and so on. The types and formats of files collected in personal digital libraries can also be varied. For example: text files, HTML files, DOC(WORD) files, WPS files, graphics, and even dynamic pictures, music and other files. The type of "book collection" can be said to be "small and complete". In a word, personal digital libraries can focus on the construction of multi-type, multi-format, multi-language and multi-code information hybrid libraries according to the same theme. Although the library structure is messy, it is really close to personal needs. Therefore, it is necessary to establish a personal digital library and make it a useful supplement to the public digital library. The coordinated development of personal digital library and public digital library is an important development direction to meet the all-round information needs of individuals.
Building Six Personal Digital Libraries
6. 1 hardware. Personal digital library is based on personal computer. Therefore, personal computers are the material basis for building personal digital libraries. The configuration of personal computer's hard disk, memory and central processing unit (CPU) should be optimized as much as possible. Personal computers must also be connected to the Internet. Because the rich information resources on the Internet are the main information sources of personal digital libraries. In addition, most personal digital library system support is tied with IE. Only when the personal computer is plugged into the wings of "Internet" can it soar freely in the infinite network world, update downloaded web pages and other contents at any time, and keep pace with the times.
6.2 Software. There are many softwares that can be used to manage full-text databases. When choosing the software suitable for building a personal digital library, we should follow a basic principle, that is, the software is free or basically free. Under the guidance of this principle, dozens of management softwares for building personal digital libraries can be collected through online surveys. At present, the full-text database management software suitable for building personal digital libraries is basically mature and can be downloaded and used for free or basically free. This kind of software is basically reliable and promising, and there is follow-up guarantee online. Generally, there is an export function. Even if individual software stops updating halfway, its data can be exported to other software.
6.3 Requirements for the quality of the builder. Although it is easy to establish a personal digital library, in order to build it well, builders must have considerable information literacy. Builders should be proficient in basic computer knowledge, network communication knowledge, common software installation and maintenance knowledge and information retrieval and utilization knowledge; The builder should have the ability to download, link, input, manage, retrieve and output digital document information; The builder should be able to use all tools, methods and opportunities to collect literature information on related topics, track the latest trends and update the content in time. For example: learn to log in to various public digital libraries, various related databases and major portals; It is necessary to closely track the latest information trends of relevant academic forums, newsgroups, academic conferences and special lectures; Attention should be paid to collecting specific information such as academic journals and monographs.
Personal digital library is a new thing, and there are still many problems worthy of further study. For example, the concept of personal digital library needs further analysis; The relationship between personal digital library and public digital library, and how to coordinate development, so that the two complement each other and go hand in hand; Personal digital library involves the digital copyright of documents, the copyright of downloading links of network information and the copyright of various databases. I just want to attract more people of insight in the library field to pay attention to the future development of personal digital libraries.
