  • Everyone is invited to purchase the published versions within his/her budget.
  • I don't earn much by writing books: the point is to help propagate the values of Open Knowledge to the authors and publishers in China, as well as to prove its profitability.
  • New or revised editions will only appear after the old ones are sold out, so your support will really make a change.
