ABSTRACTToday most of the library is using either manual system for tracking the day to day

activity or they are using desktop, spread sheet like MS Excel application to manage

the day to day activity. In this proposed Library Management System it will run in

client server mode and user can check the book availability, they can search the books,

library staff can issue, receive book, and management can check the report. System will

store historical data. Management can anytime view the total book status, library card

status.

This project of “LIBRARY MANAGEMENT SYSTEM” of gives us the complete

information about the library. We can enter the record of new books and retrieve the

details of books available in the library. We can issue the books to the students and

maintain their records and can also check how many books are issued and stock

available in the library.

Keywords: library management, automation in library.

1. INTRODUCTION

“Library Management Software” is to handle the entire activity of a library. The

software keeps track of all the information about the books in the library, their completedetails and total number of books available in the Library. The user will find it easy in

this automated system rather than using the manual writing system.

In this chapter, we will explain the objectives, scope, limitations and constraints faced

by library management system.

1.1 Project Overview Statement:

Library Management System is an application refer to other library system and

it is suitable to use by small and medium size library. It is use by librarian andlibrary admin to manage the library using a computerized system. The system

was developed and designed to help librarian record every book transaction so

that the problem such as file missing or record missing will not happened again.

Throughout the project the focus has been on presenting information and

comments in an easy and intelligible manner. The project is very useful for

those who want to know about Library Management System.

Library management System is a very simple, flexible and user-friendly

Library Management software specially for INDIA, that takes care of all your

requirements relating to managing huge library. Library stores complete

records of the books, members, creates library card, mange transaction,

Computes late fine, search books and generate MIS reports.

It is a complete library solution make this complicated function look much

easier. The software is user-friendly, with user-definable preferences like Book

category and extensive and search facilities, huge library of periodical data to

analyze the trend of issue and receive of books.

1.2 Project Goals And Objectives:

The project aims and objectives that will be achieved after completion of the

system.

To eliminate the paper-work in library

To record every transaction in computerized system so that problem

such as record file missing won’t happen again




7

To design a user friendly graphical user interface which suit the users

To complete the system according to project schedule

To produce technical report that documents the phases, tasks and

deliverables in the project

1.3 project Scope and Features:

The Library Management System is designed & developed for a receipt and

issuance of books in the library along with the student’s details. The books

received in the library are entered in Books Entry form and the new student is

entered in the student entry form. When the student wants to get the desired

book the same is issued on the availability basis to the student. The issuance

and due date for the returning of the book is also entered into the Book Issueform under third menu Book Issue.

Any education institute can make use of it for providing information about

author, content of the available books. It can be used in offices and

modifications can be easily done according to requirements

From an end-user perspective, the Library Management System Project

consists of two functional elements: Master and Transaction Module.

Master and Security module

Master and security module includes user security management, login security,

book details, member master, library card, library transaction.

Login :Check the user by user name and password, All user needs to

enter user name and password to access the system, system check the

user name and password and give access the system resource only valid

user.

Main Screen : It display available options, menus and toolbars to the

logged user. System display option as per user rights. It also show the

name of user currently logged in.

Book: includes book master, search book and book status.

New Book : This form used to enter new book details, system generates

book id,. User enters book title, book author, publisher name, book

description, no of pages, book category.




8

Display Book : It displays all books in grid, user can short the book by

book title, book author, category. User can also print all or selected

book details from this screen.

Book Status: to displays book issue and available. Modify Book :User can edit previously saved book details in this

screen.

Search Book: Library system needs powerful book search facilities to

find any book. System provides two types of search facilities one is

normal search facilities where user enter book title, author name,

category, keyword, system perform pattern search and display the result

in grid. New Member : This form used to create new library member, user

enter library member details. System generates member id.

Modify Member: In this screen system users modify existing member

details

Search Member: System provide powerful search facility to search

library member, user can search card by giving various search input like

member id, member name. System can search single for single search

condition or all condition. After search results will display in grid.

Change Password: Currently logged user can change his or her

password from this form, before system validate old password.

User Master: Administrator can creates new system users from this

form, Administrator enters new user name, password and selects user

type to create new user.

Transaction module:

Transaction module includes issuing, receiving book and transaction report.

Issuing Book : This form used to issue book to the member. In this

screen user selects book id, and member id, system display the book

and card history. If book is already issued it display message and details

of last issued details. Same way system display card history for the

member id, if book already available it shows the message. If book is

available and there is no book pending for received then book is issued




9

and system saves the details. System also has powerful search facility

to find the book and member id.

Receive Book: In this screen user enters the book issued transaction no,

system displays the transaction details and book received status. Useralso checks the book condition and enters the remark if needed.

Transaction Reports: In this report system user can generates book

issue and book received details for single member/all members, for

single book/ all books, for the selected date or all days. User can also

short the record by transaction no, type, book id, member id.

1.4 Limitations and Constraints:

The information of all the users must be stored in a database that isaccessible by Library System.

The users access the Online Library System from any computer that has

Internet browsing capabilities and an Internet connection.

The users must have their correct usernames and passwords to enter into

theLibrary System.

1.5

Assumptions:

The users have sufficient knowledge of computers.

The users know the English language, as the user interface will be

provided in English.

Microsoft SQL server to store the database.

Netbans to develop the Product.

2. Literature Review

Library is regarded as the brain of any institute; many institutes understand the

importance of the library to the growth of the institute and their esteem users (students).

Library Management System (LMS) supports the general requirement of the library

like acquisition, cataloguing, circulation. An LMS usually comprises a relational

database, software to interact with that database, and two graphical user interfaces (one

for patrons, one for staff). Most LMSes separate software functions into discrete

programs called modules, each of them integrated with a unified interface. Prior to

computerization, library tasks were performed manually and independently from one

another. Selectors ordered materials with ordering slips, cataloguers manually

catalogued items and indexed them with the card catalog system (in which all

bibliographic data was kept on a single index card), and users signed books out

manually, indicating their name on cue cards which were then kept at the circulation

desk. Early mechanization came in 1936, when the University of Texas began using a

punch card system to manage library circulation. While the punch card system allowed

for more efficient tracking of loans, library services were far from being integrated, and

no other library task was affected by this change.

By the mid to late 2000s, LMS vendors had increased not only then umber of services

offered but also their prices, leading to some dissatisfaction among many smaller

libraries. At the same time, open source ILS was in its early stages of testing. Some

libraries began turning to such open source ILSs as Kohaand Evergreen. Common

reasons noted were to avoid vendor lock in, avoid license fees, and participate in

software development. Freedom from vendors also allowed libraries to prioritize needs

according to urgency, as opposed to what their vendor can offer. Libraries which have

moved to open source ILS have found that vendors are now more likely to provide

quality service in order to continue a partnership since they no longer have the power

of owning the ILS software and tying down libraries to strict contracts. This has been

the case with the SC LENDS consortium. Following the success of Evergreen for the

Georgia PINES library consortium, the South Carolina State Library along with some

local public libraries formed the SCLENDS consortium in order to share resources and

to take advantage of the open source nature of the Evergreen ILS to meet their specific

needs. By October 2011, just 2 years after SC LENDS began operations, 13 publiclibrary systems across 15 counties had already joined the consortium, in addition to the




11

South Caroline State Library. Librarytechnology.org does an annual survey of over

1,500 libraries and noted in 2008, 2% of those surveyed used open source ILS, in 2009

the number increased to 8% and in 2010(most recent year available) 12% of the libraries

polled had adopted open source LMSs.Library project system that offers many flexible and convenient features, allowing

librarians and library users to maximize time and efficiency. Library System gives the

all detailed information about students, staffs and books. It will track on the how many

books available in library and books issued to the students. It shows popular book

among the students. It will provide book lost in library. It keeps the record of the

suppliers and book binders. It generates MIS reports for management. Our software is

customizable for any library requirement.

3. FEASIBILITY STUDY

3.1 Purpose Of The Feasibility Study:

The feasibility study proposes one or more conceptual solution to the problem set ofthe project. In fact, it is an evaluation of whether it is worthwhile to proceed with projector not.

Evaluation of feasibility of such solutions. Such evaluation often

indicates shortcomings in the initial goals. This step is repeated as the

goals are adjusted and the alternative solutions are evaluated.

Feasibility analysis usually considers a number of project alternatives, one that is

chosen as the most satisfactory solution. These alternatives also need to be evaluated in

a broad way without committing too many resources. Various steps involved in

feasibility analysis are:

To propose a set of solution that can realize the project goal. These

solutions are usually descriptions of what the new system should look

like.

3.2 Justification For The Proposed System:

Justification means convincing stakeholders that a certain development makes sense

and that it should be supported. The main justification for the transition towards digital

libraries is that it is inevitable. The entire information scene is moving towards digital,

networked distribution of information. Libraries cannot lag behind or they will be at

risk of extinction.

Is this sufficient justification, however? Certainly not, for it could be argued that in the

networked world of the digital information society there is no need any more for

libraries. More thorough justification is required, and this should be directed towards

the various stakeholders of the library:

For the user of the library, the library system should provide clearly

enhanced services, improving the availability of useful information, the

speed of access and delivery, the usability of information, etc.

For the funders of libraries, the benefits of digital libraries should be

expressed in terms of more effective use of available (financial)

resources.

The final stakeholder is the library itself, or more specifically: the library

staff. Without commitment and involvement of library staff, the move

towards the digital library cannot be successful. Justification in this




13

respect means convincing library staff that the outcome will be a more

stimulating, professional environment in which to work.

Justification of library projects should therefore concentrate on these three aspects:

enhancement of service to the user and added value to the organisation, more efficientuse of funds, and the continuation of a challenging and professional working

environment for library staff. Proposals for library projects should outline their benefits

in terms of these aspects.

3.3 Economic Feasibility

Economic Feasibility an evaluation of development cost weighed against the ultimateincome of benefit derived from the development system of product. In economic

feasibility, cost benefit analysis is done in which expected cost and benefits areevaluated.

3.4 Technical Feasibility:

Technical Feasibility includes existing and new H/W and S/W requirements that arerequired to operate the project using Netbeans. The basic S/W requirement is java in

which the front end of the library management project has been done. The basic entry

forms are developed in Netbeans and the data is stored in the MY SQL.

3.5 Desired System Functionality:

The Library System provides online real time information about the books available in

the Library and the user information. The functions of the system include the system providing different type of services based on the type of users [Member/Librarian].

The member should be provided with the updated information about the

books catalog.

Provisions for the members to borrow the books they want, if all the other

required rules hold good.

The member is given a provision to check his account information and

change the account information any time in the given valid period.

The members are provided with the books available roster and allowed to

choose the books, which they want to use in the coming up days.

The librarian can get the information about the members who have borrowed

or returned the books.

The librarian is provided with interfaces to add/edit the books available in

the book catalog.

5. REQUIREMENT ANALYSIS

In this chapter, we will discuss and analyses about the developing process of Library

Management System including Software Requirement Specification (SRS).

5.1 System Requirements Analysis:

General Description

Product DescriptionLibrary Management System is a computerized system which can helps user

(librarian) to manage the library daily activity in electronic format. It reduces

the risk of paper work such as file lost, file damaged and time-consuming. It

can help user to manage the transaction or record more effectively and time-

saving.

Problem Statement

The problem occurred before having computerized system includes:

File lost :

When no computerizes system is implemented, the file always lost

because of human and environment. Sometimes librarian didn’t keep

the record to its original place because of a lot member queue up to

borrow books. After that the file was missing due to messy

environment.

Difficult to search record :

Without computerized system, when member wants to borrow a book,

librarian hard to search for the member’s record. It will cause time-consuming when a lot member are waiting to borrow the books.

Cost consuming:

Paper is needed to add every new record. After a long period of time,

the cost to buy a paper can be high. On the other hand, library needs to

employ more staff to solve the long queue problem. If the library only

has one staff, it is not enough time to process the book transaction.

System objectives

Improvement in control and performanceThe system was developed to overcome the current problem occurred

in library. The system must be able to validate the user, store the record

and bug free.

Save cost

After implementing the computerized library system, library can only

hire 1 or 2 staff to handle the book transaction process. With the aids of

computerized system, library can save the cost of hire employee and

also save the paper-cost.

Save time




18

Librarian is able to search the record in short time by pressing only few

keys. Compare to previous time before implementing the system,

librarian can save a lot time.

6. SYSTEM DESIGN

6.1 Application Architecture Design:

The three tier architecture:

To develop software for Library management system the architecture that we areimplementing is Three Tier Architecture. The User Interface Layer, Application Logic

Layer and Data Storage Layer together called as Three Tier Architecture.

User Interface Layer

The User Interface Layer will consist of everything shown directly to the client. This

Layer will communicate only with the Application Logic Layer. This Layer will also

be responsible for initial validation of any user inputted data. Any validation that

requires communication to the Data Storage Layer will however be completed at the

Logic Layer.

Application Logic Layer

It will be responsible for providing a secure connection to the Data Storage Layer and

formatting information received from the SQL Server for presentation to the UserInterface Layer.




22

Data Storage Layer

The Data Storage Layer will record all information required by the Logic and User

Interface Layer. This data will include Subject details for general user and admin user

information. Within the Data Storage Layer a collection of SQL Queries will provide

access to the data in a meaningful way.Data Flow Diagram :

6.2 Database Design:

The LMS implements MySql as the Backend and thus the database schema is

defined and modified through MySQL Query Browser. The LMS consists of five

tables to store all the information, and all the necessary information is extracted

from these tables through appropriate queries in Netbanse.

Data Dictionary:

1. User table:

Table name: Lib _user

Description: store the information of user who used the library system

rulesDefault valueNull/not nullData typeFields

--not nullVARCHAR(45)User _Name

--not nullVARCHAR(45)User

_Password

--not nullVARCHAR(45)User _Type

--not nullVARCHAR(45)User _Active

2. Book master table:

Table name: Lib _book _master

Description: store the information of books


- Nullnot nullINT(10)Book _id

- Null-VARCHAR(100)Book _title

--not nullVARCHAR(100)Book _author

--not nullVARCHAR(100)Book _publisher

--not nullVARCHAR(45)Book _publish _year

--not nullVARCHAR(100)Book _category

--not nullVARCHAR(250)Book _keyword
