the optional audio book thing

I've looked at the World ebook fair site - not bad and at least I know it exists! Some interesting titles - I was surprised by the range. I don't think I can read an ebook as I find reading a screen really taxing at times. I read all the time at home and whilst using public transport, but I use that primitive device called a book! Much better than electronic - saves batteries and the planet! I'm not using batteries that cause acid to leach into the soil....that's my logic. I know that producing a book causes untold problems - I enjoy them and will keep enjoying them until I can't! So there!!!!!
