Collectible collection.

Sony releases limited edition Bob Dylan collection in Europe.

Last year, without any fanfare, Sony released a very limited Bob Dylan collection called The 50th Anniversary Collection -- for a very specific reason.

The four-CD set contains 86 songs that he recorded in 1962, including numerous takes of "Baby, Please Don't Go," That's All Right, Mama, "Mixed Up Confusion" and "Sally Gal." A source at Sony says, "This isn't a scheme to make money. 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. But it wasn't the right time to do it right after he released [his latest album] Tempest. There are other things we want to do in 2013, though."

There are about 100 copies of this release out there, and some have made their way onto eBay in excess of $1000.
