## Overview

BEL Library Management System is documented as a Classic ASP/VBScript application using ADODB and MySQL. Its main user workflow is authentication followed by library operations: browsing and maintaining the catalog, handling loans and returns, and submitting book requests. The tree also exposes administration, dashboard, and feedback pages. The sampled source is limited to browser-side scripts and a third-party validation library; consequently, links between ASP pages and database operations are inferred only at the broad level documented by the README, and specific page-to-page or query wiring is not shown.

Main entry points: [`LibraryManagementSystem/includes/db_config.asp`](https://github.com/dinesh31r/library/blob/main/LibraryManagementSystem/includes/db_config.asp) (Database connection), [`LibraryManagementSystem/login.asp`](https://github.com/dinesh31r/library/blob/main/LibraryManagementSystem/login.asp) (Sign in), [`LibraryManagementSystem/dashboard.asp`](https://github.com/dinesh31r/library/blob/main/LibraryManagementSystem/dashboard.asp) (Dashboard), [`LibraryManagementSystem/books.asp`](https://github.com/dinesh31r/library/blob/main/LibraryManagementSystem/books.asp) (Book catalog)
