Keeping good books is my little habit. After reading, I like to collect those books. In the past, I always keep paper books, so I have a big bookcase, when I move home, these books take me a lot of time. What make me so grief is that, sometimes they are ruined by worms. Jesus! I think laputa is a good helper. I down lode every books I like, classify the books according to my own preference, read everywhere I want, and never worry about my books could be broken by the damn bugs.I hope everyone will like it.
