Advantages of the number of books and magazines in the digitization of ancient books Since the mid-1980s, China has begun to digitize ancient books, from simple full-text scanning images, to making bibliographic databases, developing various search tools, and now to the full-text digitization of ancient books archives. After such long-term exploration, Has achieved a lot of achievements, but also accumulated a wealth of experience. At present, the digitization of ancient books has generally the following four ways: Full image mode. This is the simplest way to digitize. Simply scan the ancient books file into an image and store it on the storage medium. The text is stored in an image format such as BMP, JPG, TAG, GIF, etc. The digital version of the ancient books file obtained in this way is called "full image version". The full-image version is intuitive, fast, and practical, but there is no index relationship between text and images. It is impossible to directly retrieve the contents of ancient books and it is not convenient to find. Directory text, body image mode. This is an improvement on the "full image version". The directories are all stored in text, and the body part is stored in an image format, and an index relationship between the directory and the body is established. Readers can search and find at the directory level, and can find the desired body image based on the index relationship between the directory and the body. The directory here can be regarded as a generalized directory, which includes the name of the file, the title of the book, the size of the title, and the name of the figure and the name of the table. The digital version of the ancient books in this way can be called the "title search version". Full text mode. The Title Search Edition only implements directory-level retrieval and lookup issues. The full text method is to store all the texts in the book in text form. It belongs to the digital book in the true sense, which can realize full-text search and search. This digital version of the ancient books is called the "full-text version." The full text graphic comparison method. This method is a combination of the above methods, and is also a method commonly used by archivists of ancient books. It stores ancient books in images and texts, and also indexes each Chinese character in the ancient books and its images in the original book. Users can search, find and read ancient books in the full-text version. It is also possible to quickly and conveniently "flip" to the corresponding position of the current text in the "Full Image Version". The digital version of the ancient books file obtained in this way is called the "text search version". "Graphic Search Version" is the most ideal digital method at present. It can read texts, search, and observe original texts, and read the font writing and layout features of ancient books. The number of books and magazines can easily solve the above four digitization methods.
