电子书是指将文字、图片、声音、影像等讯息内容数字化的出版物和
植入或下载数字化文字、图片、声音、影像等讯息内容的集存储和显示
终端于一体的手持阅读器。代表人们所阅读的数字化出版物，区别于以
纸张为载体的传统出版物。电子书通过数码方式记录在以光、电、磁为
介质的设备中， 必须借助于设备来读取、复制和传输 。
正如电子邮件改变了我们彼此写信的方式一样，电子书正在改变我们的阅读方式。我们可以很容易地从因特网上下载新的电子书。现在搜寻文章更容易、更快，而且我们也能在电子书上做笔记。此外，它们节约了大量的纸。但是电子阅读器仍然比纸质书昂贵得多，所以不是所有的人都能买得起它们。然而，随着电子技术的飞速发展，阅读电子书的成本将变得越来越低。许多人认为在不久的将来，电子书将会比纸质书多。
