Sony, the other major player in the e-book game, so far only has an archive of 100,000 volumes. But it has been working with Google to allow people to use the Sony reader to download from among the 500,000 public domain books (those without copyrights or patents) that the search engine can access.
至於電子書的另一大玩家── Sony Reader，雖只有 10 萬冊數位藏書，近日卻積極與 Google 合作，希望能開放其圖書搜尋中的 50 萬種無版權或無專利的「公有領域圖書」，以供使用者下載。
