Well, I'll explain the difference to you.
The library "loans" a copyrighted CD to an individual for the individual's listening pleasure. If the individual illegally copies the loaned CD, that is strictly a violation of the law by the individual, and not by the library.
Someone who puts a copyrighted song on their computer to be "shared" knows that anyone who obtains a copy by downloading is violating the law. The "sharer" has no right to put a song out to be downloaded because he does not own the copyright. And, the song offered for download was most likely illegally downloaded from another "sharer" on the file "sharing" network. '
Thats exactly my point. Thanks for reinforcing. The person who makes the illegal download is responsible, not the lender. In the case in question, Tannebaum is the lender library.
