But those books were printed on different paper. I have books that are between 100 and 150 years old and the paper looks fine. However, I also have paperbacks that are about 20 years old and look as if they won't make it another 20.
I have ordered an e-book reader after loooong weighing of the pros & cons. I don't think I will switch to electronic books completely, because it's just not the same (bf already has a reader and I borrowed it for a couple of days to see how it feels). I will still buy books that I want to be able to hold in my hands (favourite authors) and illustrated book. I will also buy the murder mystery books that I share with a couple of colleagues (we take turns buying them and then hand them on).
However, a couple of months ago we did a very difficult but somehow also exciting thing: we put ALL the books we didn't want to read again or didn't want to read at all into boxes and gave them to the charity shop. There were so many there that just took up space. They weren't good or beautiful and really not worth keeping - at least not for us, somebody else might love them, so we set them free.
I want to use the reader mainly for holidays. We tend to take a long summer holiday each year and I always need lots of books for that. If we go to a country where it is easy to get books in English or German the only problem is that I end up carrying a couple of kilos of books around with me. In countries where I don't speak the language well enough to understand books it means serious trouble - nobody wants to spend time with me when I'm bored, not even I. With an e-book reader I can "pack" hundreds of books and people around me can relax.
