I. Introduction:
 Documentation was conducted to present an overview about the library
system of the QuangNam University of Pedagogical and the mode of
operation is happening and the problems is happening in order to make
a new plan to improve the system.
 Project Name: upgrade and development of university library systems to
borrowing books.

effectiveness in managing loan books, return books and to integrate
website in the system.
II. Referenced:
 The system documentation for new users of software.
 For questions or encounter errors that users can also refer to the
instructions online through the hotline.

system to increase effectiveness in managing loan books, return
books and to integrate website in the system. So the software
system will hepl in job manage library become simpler and more
efficient.
1. Justification of changes:
