LIBRARY MANAGEMENT
SYSTEM

🙢
▪ This system, it is basically concerned about
managing the order of books in library
▪ It has 2 section:
LIBRARIAN: It allows the administrator to
handle all
activities.
USER: It allows the user to choose book
▪ It improves the method of managing the
arrangements of books
INTRODUCTION

🙢
ADVANTAGES:
1. It keeps the record.
2. Improves method of handling books
4. Reduction of errors.
APPLICATION:
1.Highly Secure, Scalable & Reliable
2.Can be used in any library

� This project provides a computerized version of library
management system which will benefit the students as
well as the staff of the library.
� It makes entire process online where student can search
books, do book transactions.
� It helps managing the system very efficiently and
conveniently.
� There is a future scope of this facility that many more
features such as student login where student can login,
can see status of request for book.
