## Overview

This is a small, Windows-oriented, console Library Information Management System. Users enter through the main menu, then perform catalog and borrowing tasks; administrators authenticate before managing books and other system functions. The program stores catalog, member, and borrowing information in text files. The README gives little feature detail, and the C excerpt is partial, so the graph keeps unsampled menu wiring broad and avoids asserting specific links for unseen operations.

Main entry points: [`fuujiro_LIMS.c`](https://github.com/iamjarryfeng/lims/blob/master/fuujiro_LIMS.c) (Menu and dispatch), [`library.txt`](https://github.com/iamjarryfeng/lims/blob/master/library.txt) (Catalog records), [`infomember.txt`](https://github.com/iamjarryfeng/lims/blob/master/infomember.txt) (Member records), [`memberbook.txt`](https://github.com/iamjarryfeng/lims/blob/master/memberbook.txt) (Borrow records)
