To be more specific, third parties submit public domain works for distribution as Kindle books. Some people put a $0.00 price, other people specify a non-zero price. Amazon puts it all on there.<p>A given public-domain text may be represented on the kindle store many times over, submitted by different parties, with different formatting, at different prices.<p>As a kindle owner, I don't so much mind that there are Gutenberg-sourced public domain texts on there for sale: Maybe a $.99 one is formatted better than the others.<p>What I mind is that the kindle store is spammed full of such stuff.<p>The example that bugs me most is the person who took the ten years of Samuel Pepys' diaries, split them up into 120 ebooks each containing one month's worth of diary entries, and put them on the store.<p>I don't recall if they were charging for them or not, but I was browsing the "history" section of the store, and hit a seemingly never-ending span of one-month Pepys Diaries. Many screens full. On a slow kindle display.
