First, the digital collection and its characteristics Digital collections are the sum of the information resources stored in the library collection in digital form and available through computer networks (such as foreign language databases with only network access rights, and other forms of virtual collections). The digitalization of collections is the fastest and most dynamic digital resource compared with traditional libraries. It differs from traditional collections in terms of access forms and service methods, and its high degree of shareability and freedom from time and space. This has led to an increasing emphasis on the construction and development of digital collections. Compared with traditional collections, digital collections have many advantages such as shareability, ease of organization and storage, convenient and fast retrieval, unlimited use of time and space, and small space occupied by the premises. They also have strong dependence on equipment and environmental requirements. High, vulnerable, and difficult to manage. For university libraries with storage as their main goal, digital collections have been given an irreplaceable historical mission. Digital collections will become the main pillar of information resources protection for colleges and universities, and become the preferred information resource for users. It is teaching and researching in universities. The need for document protection is playing an increasingly important role. However, due to the lack of scientific digital collection development strategy guidance, there are problems such as lack of long-term planning and low optimization. Therefore, the library must study and formulate reasonable and scientific digital collection countermeasures according to the characteristics of digital collections, and better guide the construction of digital collection system with the principles and strategies that are compatible with the characteristics of digital collection and new environment. Second, the digitization of the collection bibliographic data The library's paper documents and other carrier literature information are built into a bibliographic information database for direct use by users. This is the basis for digital libraries to realize networked services, interlibrary loan, and resource sharing. There are roughly three types of databases currently in use: catalog, relational, and full-text. Among them, the catalogue type investment is small, the requirements for software and hardware equipment are low, the query speed can be quickly increased, and the book cashier circulation is assisted, but the original document cannot be obtained through the network is its biggest drawback. The construction of the bibliographic database is mainly taken or self-constructed, or the standard bibliographic data collection, or the combination of self-construction and self-construction. The catalogue and self-built bibliographic databases have their own advantages and disadvantages. The standard bibliography of the catalogue has more entries, and the data is generally more perfect, but subject to the construction speed of the standard bibliography. Self-built bibliographic database, the construction speed can be controlled flexibly, but the collection of bibliographic information is large. In the process of data entry, the quality is not easy to control, so the data is not standard enough, which affects the effect of online communication and sharing. Therefore, we should adopt a combination of self-construction and self-construction, and have a standard bibliographic purchase package. There is no standard book for self-construction, and we can learn from each other to achieve the best results. How to scan a book?
