图书信息管理与读者信息管理相似，共包括两部分，图书添加和图书查询与修改，图书信息添加要求正确输入图书的八项信息，并且ISBN编号唯一，实现过程中要将ISBN作为主键。下面看实现过程：
数据库中书籍：
添加书籍过程：
数据库内容增加：
图书的查询与修改：查询过程可以根据不同的条件查询，如ISBN，作者，出版社，图书名称等，默认将所有图书全部显示在列表中，输入查询条件后再表格中显示查询结果。
本模块用到标签面板，可以很方便的查询所需要的信息。修改过程输入ISBN编号后按回车键将在下方显示所有的图书信息，然后修改图书信息后所有内容就会更新。
图书查询：
图书信息修改：
添加图书源代码如下：AddBook.java
