go out of business? no. I know book lovers, and I'm in high school.
So, there will still always be a demand for them by the people who prefer the feeling of a book in hand.
Also, as of now, there aren't many digital libraries (as far as I'm aware... actually, they probably just aren't so mainstream yet).
But I feel it will be a long time before the end of books. I just don't like reading from an electronic device for an elongated period of time.
There will always be a market for rare and old books.
Plus there are at least 2 generations with legs (at least 30 years or more to live on average) who prefer them.
I am a voracious reader who uses both electronic and paper. I might be 100% electronic except for two things that both revolve around the concept of sharing: (a) the library and (b) book exchanges. People who read by the gross often buy books and give them to other people who give them their books in exchange...although the exchanges are not always "even" by design so they are not necessarily bartering situations.
On the other hand, the Kindle blew away my other reason for needing a bookstore in relatively short order. Browsing and impulse buying is now easier electronically...
So...
ask me again if magazines and newspapers stop being printed in any form.
Sadly, I think bookstores will end up going out of business. I absolutely love them, so it will be sad to see them go With places like Target and Walmart selling cheaper paperback books, bookstores really don't stand a change. I know the one in my small town went out of business. Now I have to wait to go to a bigger city on vacation to stock up on books. Also, things like the Kindle make it more convenient to get your books electronically. People want to have things as easy as they come, so I can't imagine bookstores staying in business throughout the next decade Honestly, I'd give them another 5-8 years.
Never, because no matter how many ignorant people enter into this world, there will always be the great few who can appreciate the enlightening power of books and condemn the idiosyncrasies of technology.
