I have no preference - each has its' advantages and disadvantages and I read both formats. In general, an ebook is cheaper than a hardcover, and sometimes cheaper than a paperback book. There are still plenty of places to find free content for ebooks, including the library and onlines sources like Amazon and Gutenburg Project.
It is a great way to experience new and upcoming authors, as many offer their titles for under $2 and, in some cases, free. It is certainly a greener option, especially if you are one that will keep a completed book on a bookshelf or in a box or don't otherwise pass it along to someone else to read. And the ebooks are a little bit easier to read when travelling or eating - you only need one hand free and it is usually easier to click or swipe to the next page than flip a page.
However, it is also nice to see a bookshelf full of your favorite authors and books and you do have the feel and smell of a book. Also, you don't need to ocassionally plug in a paper book. Sometimes, it will depend upon the environment I will be reading in.
For travel and bedtime reading, I choose the ebook. If I have time to sit in a comfy chair, then a paper book would be preferred. And like another commenter, I also enjoy audio books, which is all I listen to when I am driving by myself.
I'll pretty much take a book however I can get it - doesn't matter what format.
My preference is audio book on CD or DRM free mp3 like podiobooks and LibriVox I like dead tree books more than ebooks dead tree books take up a good deal of room and cost money to move long distances but can easily be loaned can read another in the collection when someone is reading one. Ebooks are cheap to move and indie authors can sell licence to ebook for under $5 that would cost over $25 for a short run on dead tree book ebooks give near instant access to most books in Public Domain through Project Gutenberg the biggest downside of ebooks is you licence them more than you own them like dead tree books I do not think either is better but both have advantages and dis advantages Dead Tree Books more likely to survive the zombie Apocalypse and maybe we should have stayed with stone tablets or scrolls.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
