Library Management System

A Python command-line Library Management System built with Object-Oriented Programming (OOP).

The project currently supports book and member management with JSON-based data persistence. It is still a work in progress, with more features and improvements planned.

Features

Book Management

• View all books
• Remove books
• Update book details
• Store title, author, ISBN, category, and copies

Member Management

• View members
• Remove members
• Update member details
• Store member ID and membership type

Data Persistence

• Save books to library.json and members to members.json
• Automatically load saved data when the program starts
• Reset library data on demand

library.json and members.json are used for local data storage and are generated automatically when data is saved.

Current Status

Work in Progress

The core book and member management features are implemented, but the project is still being developed. More functionality, validation, and code improvements will be added.

Expected Future Improvements

• Book borrowing, renewing and reserving
• Search functionality
• Better input validation
• Library statistics (most borrowed books, active members, etc.)
