主要功能简介
此系统主要面向读者用户、管理员、主管三种使用者，通过账号识别使用者身份(用户账号以2开头，管理员以1开头，主管以A开头)，具有如下图所示的功能，并且能根据使用者的操作，实时地修改系统的.csv文件，记录书库中书籍信息的变化或者人员信息的变化，具体的功能展现请见功能演示视频。

程序评价
本程序实现了图书借阅系统的基本功能，但仍然有很多可以改进的地方，以下是作者认为程序仍存的缺陷，今后有机会的话会继续完善：
- 程序无记忆性，一旦打开就不能关闭，否则所有操作记录均会被清空，系统回到初始状态
- 需要手动输入图书或用户信息进行借阅、还书、预约等操作，无法做到自动化识别
- 账户一旦注册不可注销，导致用户数量只增不减
- 没能实现到期提醒功能
- 续借次数不限
- 不能识别应还日期
总结
学有所得，甚为欢喜 ~~
