I find it the statement of law regarding importation of copyright material into the U.S. Interesting. Like so much current law dealing with the issue it was clearly written when actual hard goods, e.g. music CD's, were the issue. For a digital e-book file on a computer drive how one determine that is, or is not, for personal use only and not for sale or distribution? Never mind the fact that anyone with half a brain would know to change a file name from say twilight.epub to mynotes.txt.
