According to Mortimer J. Adler’s essay “How to Mark a Book”. There is a great power in books that most people don’t know about. He states that once a person learns how to use a book in a correct way he will have much more power than people that do not know how to do it, when he says this, he means that one should know “how to mark a book”, but what does this mean?. Well throughout his essay he gives examples on how to do it, or scenarios that encourage us to do so. He believes that anyone that owns a book and reads it did not completely used it or read it fully if he did not made marks on it. For example he says that when one is reading we should be highlighting, marking, writing, and circling any questions the one has, any words that we did not understand or write notes that will help one comprehend the book better. He also says that books are meant to be used at fully, that if a book still looks new after reading it was not used at all. Therefore, one should make those books look old, to make them look that they were put into work. Finally he states once we buy a book it becomes part of our body, that we should never let anybody borrow or have any of our books, because after we have fully used them they will have all of our thoughts , and personal information that should only be keep for our own studies. I totally agree with Adler. After his article, I started my marking my books. I will say the book inspired me in way, now when I read, I highlight the words that I do not understand and write their definitions on somewhere on the same page to understand what im reading. I have also started writing notes on them, and I could see a great improvement in my comprehending and writing skills. Plus my vocabulary has grown. Ever since I read his article, I stop letting my friends or classmates borrow my books, because I don’t want them to take any valuable information that I have and use it for them. I believe that
