“Unavailability” is the special book status reflected by State-owed Import and Export Cooperation, which means the books are unavailable to import for the time being. The reasons are most likely including as followings:

  • The status has not updated on time on the website, such as out of stock, out of print, print on demand, etc;
  • Region sales restriction;
  • One book probably contains sensitive words according to relevant local regulations;
  • Other specific reasons will be updated after confirmation with publishers.
