In this digital age, research shows that books are losing a war with visual mediums for knowledge and entertainment, such as videos and games. On the bright side, new technology has only made books more accessible than ever, giving users the freedom to choose between different novels or textbooks with the press of a button. Whether you’re a student or vacationer, you no longer have to carry bundles of books with you wherever you go.

While a dedicated eReader such as Amazon’s Kindle gives you easy access to digital format books, not everybody can afford them or want to carry them.
