PREFACE Library is a treasure house of knowledge. A well organized library is an asset to the school, college, university or the neighborhood. A library is concerned with books, reference, , and many other issues. Thus the process of handling a library manually is very troublesome and clumsy. Concerning at this point of view, the computerized system for handling the activities of library management provides a comprehensive way to lessen physical labor, to reduce complexity of the manual system and so on. This project shows a easier way to maintain the records of books, , book circulation, financial transaction etc. These facilities makes this project more useful. 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 are involved with library such as management authority, the s, and who want to know about Library Management System. We tried to include all essential features to provide best services to the s and management. All of these features can be modified according to the demand of time.

1. Introduction Since the dawn of civilization, men are trying to use the best output from the technology. “Library Management” with computer is relatively recent addition to the libraries which has turned it more easier and comfortable. “Library Management System (LMS)” is a web based solution which is developed on latest technology focused towards automating the vital activities of the Library. “The Library management system” Solution can be integrated with Barcode for easy access and retrieval of any item from the Library. An online public access catalog facility can be provided for speedy retrieval of any kind of document. This solution can be linked with self service for quick search and online requisition. Different libraries of organization or institution use the software that is designed according to their demand. We have designed a simple and effective procedure of LMS which may manage a library works so far. The different sites of this system is mentioned briefly below:

6

1.1Purpose:The purpose of this application are as follows :  The software is for automation of library.  It provides following facilities to Operator :  Can enter details related to a particular book.  Can provide hip to . :  Can read and write information about any Member.  Can update, create, delete the record of hip as per requirement and implementation plants.

7

1.2 Scope : The different areas where we can use this application are :  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.

1.3 Drawbacks of the present system Some of the problems being faced in manual system are as follows:  Fast report generation is not possible.  Tracing a book is difficult.  Information about issue/return of the books are not  properly maintained.  No central database can be created as information is  not available in database.

8

1.4 Proposed system There will be three major components :  Stock maintenance.  Transaction entry.  Reports.

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 s (students). Library Management System (LMS) s 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 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

9

with the card catalog system (in which all bibliographic data was kept on a single index card), and s 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 the number 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 Koha and 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 SC LENDS 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 public library systems across 15 counties had already ed the consortium, in addition to the 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 s 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

10

4. PROCESS DESCRIPTION The Library Project's aim is simple: make it easier for people to find relevant books – specifically, books they wouldn't find any other way such as those that are out of print – while carefully respecting authors' and publishers' copyrights. Our ultimate goal is to work with publishers and libraries to create a comprehensive, searchable, virtual card catalog of all books in all languages that helps s discover new books and publishers discover new readers. 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. The library provide a library card and ID. for every member student. 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 Issue form under third menu Book Issue. The student has to pay the fine if any on the basis of no. of days delayed deposit of the book in the library.

14

4.1Methodology:  First, we collect data from different sources about library management. We visit different libraries. We also visit different site about library management through internet.  After collecting and analyzing these data, we find out the key points which are needed to accomplish this term paper.  Depending upon these key we design a flow

diagram which shows the interrelationship among these data, management authority and s. This flow diagram is shown in the page 14.  Based upon these data and the flow diagram we write

a source code in C++ programming language. The source code and sample output are shown in the appendix.  At the starting , a welcome message is displays on the screen, three option is there for the to select to forward.  As a library keeps the records of the books, reference, students, teachers, officers, the source code take inputs these items from the operator.  In the option BOOKS all affairs related to books such as add new books, view books, search 15

for a particular book etc. are done. The process of book circulation is also need to be done from here.  In option all affairs related with such as add , view all , search for a particular member are included.  In the BOOK CIRCULATION portion the issue and return of the book is done. One need to issue a book from and return a book to the library using this option. This process also calculate the fine if the don’t return the book in due time.

fig: various aspects of library

4.2 RESULT: The program (source code) run successfully. 17

4.3 DISCUSSION:  In the source code we only array, which makes the program most simple and easy to understand.

18

 We use different features of C++ programming

language and also use many other features which are actually properties of C such as gets().  This program covers all essential aspects that a library management system does have. Thus both of the and the authority will be helped by this program.  And all of these aspects are changeable according to the demand of time.

4.3.1 LIMITATIONS:

 As we want to see whether the process we working does work properly, we only show some of the most important features of library management system in the source code. Thus many other features are not shown here. But as the source code executes properly for these features, it will also execute the remaining features.  We used only array, but we can also use file, pointer etc. to make this program more efficient. 

We didn’t use any features of graphics.

5.Conclusion

19

After completion of the term paper, we expect that the problems in the existing system would overcome. The “LIBRARY MANAGEMENT SYSTEM” process made computerized to reduce human errors and to increase the efficiency. The main focus of this project is to lessen human efforts. The maintenance of the records is made efficient, as all the records are stored in the ACCESS database, through which data can be retrieved easily. The navigation control is provided in all the forms to navigate through the large amount of records. If the numbers of records are very large then has to just type in the search string and gets the results immediately. The editing is also made simpler. The has to just type in the required field and press the update button to update the desired field.

The Books and Students are given a particular unique id no. So that they can be accessed correctly and without errors. Our main aim of the project is to get the correct information about a particular student and books available in the library. From a paper analysis of positive points and constraints on the component, it can be safely concluded that the whole management system has been made through our level best analysis. We wish our system will go a long way by satisfying s requirements. The computerization of the Library Management will not only improve the efficiency but will also reduce human stress thereby indirectly improving human recourses.
