I found some niche that I want to promote and of course I want to sell book(s) on topic.
That topic is covered on scientific sites and of course on Wikipedia from where You can get some good knowledge about that topic.
Book(s) that I want to sell are written buy scientist(s) who are well known in that topic and I do believe that there is demand on their book(s), but.. How selling such book(s) can be affected when there are free informations on topic everywhere?
I'm sort of IT guy and I'm buying books and magazines even if I know where to find same informations for free. But I like to have paper copy and I enjoy reading while I'm "offline". However, I think that people as me are in minority and therefore is my question above.
