去年年底，Bob Dylan（鲍勃·迪伦）发行了一套名为《The 50th Anniversary Collection》的唱片，该唱片收录的是1962年间鲍勃·迪伦录制的86首未发行过的歌曲。但是，由于欧洲版权法的规定，这套唱片在英国地区内无法取得版税，所以，索尼公司发行了一套限量100张的《The 50th Anniversary Collection》唱片，这张唱片的副标题是《The Copyright Extension Collection, Vol》（版权延期收藏版卷一）。 据悉，按欧洲的版权法规定，录音作品只有50年保护年限，而在美国，78年通过的法案表明，录音版权直到所有作者逝后70年方失效。2011年，欧盟更改了版权法，将保护年限增加到70年，但新版权法要到2014年开始实施。 索尼公司发行的100张限量版唱片被随机放在法国、德国、瑞典和英国的唱片店当中。一位索尼公司内部人士在接受《滚石》杂志采访时说：“这不是一个赚钱的计划， 对于1963年或者之前录制的作品，欧洲的版权法确实从50年的保护年限扩大到了70年。其实，实际上是，如果你录制的作品在前五十年没有使用过，这就意味着你不再拥有它。” Bob Dylan has released a 50th Anniversary collection in Europe only. According to Rolling Stone, around 100 copies of the four-CD, 86 track set featuring studio outtakes and live material recorded by Dylan in 1962 have been released. The set was designed to copyright the material under new European laws, a source at Sony Music told Rolling Stone. "The copyright law in Europe was recently extended from 50 to 70 years for everything recorded in 1963 and beyond. With everything before that, there's a new 'Use It or Lose It' provision. It basically said, 'If you haven't used the recordings in the first 50 years, you aren't going to get any more.'" "The whole point of copyrighting this stuff is that we intend to do something with it at some point in the future," says the source, alluding to the ongoing Bootleg Series project. "But it wasn't the right time to do it right after he released Tempest. There are other things we want to do in 2013 though." Approximately 100 copies of The 50th Anniversary Collection were available through record stores in France, Germany, Sweden and the United Kingdom. Fans were also allowed to download the collection for 100 Euros from Dylan's website. Rolling Stone reports that copies are changing hands for $1,000 on eBay.
