But the real problem most of us can't effort the costs of buying new books
I am going to disagree with that. A bigger problem is that we don't have enough time to read all the books we would like to read, even if we could afford to buy them all. In fact, there is so much free information around the Internet, such as articles, blogs,
whitepapers, manuals and even free ebooks, that gathering a lot of information is quite easy. The hardest part is finding the time to read it.
I find it easier to read books on paper, but they are too large and heavy to carry them around all day. Instead, I use ebooks or other documents that I save to a small tablet or other protable device, and I read them during idle time, such as when I am travelling
in public transport.
