A Library Management System is a system that is used to maintain the records of the library. It contains work like the number of the available books, the number of books issued, the number of books to return or renew. It helps to maintain a database that is useful to enter new books and records of books borrowed by the members with the respective submission dates. It will reduce the manual work done by the librarian to maintain the record of the library. It allows maintaining the resources in a more operative manner that will help to save the time. It is also convenient for the librarian to manage the process of books allocation. It is useful for students as well as a librarian to keep the constant track of the availability of all books in a library.
The software whose software requirement is mentioned in the system is the Library Management System .The SRS (System Requirement Specification) covers the complete description of the Library Management System and this aims at simplifying the effort of the librarian and book lenders, thus increasing the productivity by using tools that simplify the book lending process.
This Online Library Management system will be an automated one. The users would be able to search up the book, check its availability. The admin department will be able to track the status of each user, including their details and books they have issued. So, this would increase the user’s and admin’s productivity by providing a better and simpler interface to manage the system. With the advent of technology, this system can be easily implemented by libraries especially in libraries of educational institutes.
II. RELATED WORKS
Online Library Management System is an Automated Library System that handles the various functions of the library. It is an important part of every school and college and it helps the librarian to keep records of available books as well as issued books.A. J. A. Baetiong et al. shows in  that mobile and web application integrates the library process such as circulation, inventory, acquisition, and cataloging into a one web application. The mobile app helps the users to uncover books for a particular topic, borrow books and receive notification regarding due date or penalty. Recently W. Zhigang in  designs the information infrastructure and key mechanism of library management system, and discusses the innovation of system service mode from the aspects of readers' information acquisition and modification, fast management and delivery of books. In 2012, J. Hou, Z. Zhu and J. Zong in  designed the network library management system operated on the company backbone network and it consists of eight subsystems of book cataloging, book acquisitioning, book circulation, periodical management, standard management, data management, system maintenance and Web query.
A. Current/Future Requirements
Currently the software is used to keep a record of books borrowed, books available, user details.
Future modifications will be made based on user feedback.
The proposed Library Management System project will help the students and librarian to maintain the details of the library. It will assist the librarian before the shortage of books while they can know the details of the number of currently available in the library according to the author by accessing the system. A student can view the details of the book issued by them, and the system will notify the students about the last date of submission of books. At the time of issue of a book, the student will get assisted by the system about different authors of a similar book so that they can get the best available book from the library.
One add-on feature for this application is the option of providing an online notice board, this feature can be used by the librarian for uploading announcements related to an event going on in the university or any book fair which is about to hold the nearby future. Also, information like the sale of old books can be shared.
Another feature can be adding lecture notes, the teacher can create some lecture notes and upload them in pdf format in the application. So as the students will find the application more interesting and beneficial. The lecture note’s part will play a major role in gaining the popularization for this system.
