E-books become more popular than paper books. There are a number of benefits of E-books over paper books. E-books are delivered almost instantaneously. We can download and start reading them within minutes, without leaving our chair. No trees are required to manufacture paper for the pages of e-books. When we need certain information, we can get it immediately, by downloading an e-book. E-books take up less space. We practically don't need any space to store them. We can store hundreds and thousands of e-books on our computer or reading device. E-books are portable. With today's technology we can read e-books everywhere, on the bus, train, airplane, and while standing in line. E-books are searchable. We can easily search for any information in an e-book, instead of turning page after page. Since e-books are delivered through the Internet, there are no packing and shipping expenses. E-books can be printable, so that if we wish to read an e-book in the traditional way, we can very inexpensively print it with our home printer or at any printing shop. An E-library for computer science and Information Technology might help students of our country as most of the IT books of our syllabus are not available everywhere and also cost effective for us. The developed system aims to an E-Library for Computer Science and Information Technology where stored most of free source IT books sequentially with different sub categories.
