Reading Books in Printed Form. or on Computer
The popularization of computer has made it possible to read books on computer. With it, there is much discussion about whether e-books will replace traditional print-on-paper books.
Some people say they like only e-books, which are quicker and more convenient to get and use. To get a needed book, one has to spend much time or money in searching for or buying it in bookstores, but one can just type in the title, author or other related information of the book to find it in minutes on internet. Sometimes one can even read the full content of a digitized book free of charge or instantly discuss about a book in an online forum. Moreover, a lot of information of books can be stored in a small compact disc, which is easy to take.
Other people, however, think printed books are still necessary. In the first place, too much time in front of the computer can cause eyestrain or increase radiation risks. Second, a printed book can be read at your convenience. One can read in bed before sleep or during a boring journey, without fussing with a computer.
In sum, since e-books and printed books have their respective advantages and can complement each other, I would like to combine the two ways to meet different needs. For quick reference, a digitized book will probably be useful. To appreciate a poem or a novel, I prefer the traditional way of reading on printed books.
