In this tutorial, I have a full source code for Online Public Access Catalog For Library System or it's called OPAC.
Online Public Access Catalog for Library System is for viewing and providing information about books, authors, and category inside the library.
This program works to provide the students the information of the book that we're gonna borrow, to know the status of the books inside the Library, and to know if the books are available or not. And, we display the image of the book in this program. The user can search by title, author, category, copyright year and the barcode of the books.
