A library management system(LMS) is a software built to handle the primary housekeeping functions of library. LMS help libraries keep track of the books and their checkouts.
It is used by librarian to manage the library using computerized system. It has been opted by a lot of orgnizations, including a lots of schools and public libraries. To run this program you have to put the correct password which is "codewithc" .
