## Overview

This is a small React library-browsing and borrowing UI. A visitor opens the app, sees the available catalogue, borrows books subject to in-memory limits, and can return them; the app updates availability and the borrowed list. The repository also contains a separate Library page and BookCard, but the sampled entry point does not mount that page. The catalogue is static data, not a persistent database. The README describes responsive browsing and book details; no backend or persistence is evidenced.

Main entry points: [`src/App.jsx`](https://github.com/banashree19/library_managment/blob/master/src/App.jsx) (Borrowing state), [`src/pages/Library.jsx`](https://github.com/banashree19/library_managment/blob/master/src/pages/Library.jsx) (Library page), [`src/main.jsx`](https://github.com/banashree19/library_managment/blob/master/src/main.jsx) (React entry), [`src/components/BookList.jsx`](https://github.com/banashree19/library_managment/blob/master/src/components/BookList.jsx) (Available books)
