Open the installation directory of the system in the library-there is a "bookexample" spreadsheet file (mainly the header and format of this form)-and enter the book information in the corresponding column (it can also be copied to other places and then input, so I will copy several copies for others to record together, and then import them together, and pay attention to the fact that the "book number" cannot be repeated, otherwise it will not be imported)-and then enter the book management system. !
