On the Taiwan side, though, they may wonder why you brought an expensive U.S.-printed copy when you get the special rice-paper edition of "Applied Cryptography, 2nd Ed." for the equivalent of $2.25 in Taipei's book stalls.
If this were Singapore, they might consider it subversive literature, because it is :-) Don't know about Taiwan; you can tell them it's a computer textbook or math textbook if they ask any questions. Rice-paper editions of books are especially good if you need to eat them in a hurry when the Feds are raiding you....
There will be no problem to bring it to Taiwan. I think you can buy a cheaper one at Taipei, but not as cheap as $2.25. Everything there is very expensive now, except books. Unfortunately, they are not rice-paper editions. You will have a hard time to eat them. -- ============================================================================ Name : Chih-Wei Chang (Ray) Computer Science, Texas A&M University, E-mail : cwchang@cs.tamu.edu College Station, TX-77843-3112, USA. ============================================================================
