Branding and interface design specialists Information Architects present, surprisingly, seven reasons for re-reading your favorite books:

Books are people
Books are people speaking with signs. Meeting cool people several times is nice.

Good books are friends
Choose books like you choose your friends. Talk to many, stick with the best. A good book can make you happy, get you through hard times, teach you amazing stuff. It can do that every time you read it.

Meeting friends again and again is where the fun starts
Good books are a pleasure to read. Repetition of pleasure is fun.

Good friends are never boring
Do you think that if you read Kant’s “Critique of the Pure Reason” you’d get it all in one go? Kant would not.

Good stories are never fully understood
Do you think that if you read “A Midsummernight’s Dream” you’d get it all in one go? Shakespeare would not.

Good stories gain through repetition
You learn more reading “The postman always rings twice” for the 3rd time than loosing the pleasure of reading over some boring “must read” classic that doesn’t talk to you.

Repetition is yummy
Imagine a guy that eats his favorite meal just one time, because he is “afraid to get bored” or he “doesn’t have the time to eat the same thing twice”. Kids love repetition. Why do you think that is?
