Abstract: The purpose of this research is to help users navigate within libraries using an android application. Nowadays people visiting libraries has gone down. The reason is the traditional way of manually searching and finding a book. It takes a long time to search and find a book in a library, time and energy waste if the book is borrowed by someone else, should wait for the one to return, though the book is needed immediately, lack of choice of choosing a good book and lack of ways to share opinions about a book. The application will help users to search and find books so quickly and navigate them to reach the book’s location using indoor navigational techniques such as Wi-Fi localization. It will also allow users to share their opinions among other readers through reviews and chats. The borrowers will be notified if the borrowed book is wanted by someone else too.
