Good site, but it has some frustrating limitations that make it vastly less useful, specifically regarding the phenomenon in the article. The search UI doesn’t expose the release code (and many entries don’t even include it), so when it says “vinyl” you have no idea which of the possibly dozens of releases it refers to, some of which can be awful, like the article points out.

I’m willing to help fix this, but the source code is not public, and when I emailed the author I got no response.
