I've about 200 books on my kindle and there's still 2,924 megabytes of memory available. Pretty much got a classical library on there for nothing as such books are made available by volunteers like the Gutenberg project efforts.
Great stuff. It just saves me so much space. Last time I moved I had to make three or four trips to the charity shop with a full large wheelie suitcase. Probably doubled their stock. I'm saving a lot of money as well as kindle versions are cheaper than bookshops.
Think National. Act Local. Oh- and superstition is just the dark matter of human history.
