You will be able to search and display in a series of operations. Further, registration in a book management database for managing book information can be performed by an extremely natural and simple procedure.

Although book metaphors and electronic books are attractive as new expression media in their own right, when the amount of information described in this way has increased to the level of the current books, the book information is different for each. It is expected that there will be a flood of external media that stores data, and that users will not be able to use it unless they perform a troublesome operation that takes the file management of the computer into consideration.

Using the electronic library system of the present invention,
By solving these problems, it becomes possible to freely access the information described in the book metaphor, which is extremely convenient for users, and the attractiveness of the book metaphor and electronic books increases the It will also contribute to the spread and refinement of the method.
