Well, we knew this was coming: Amazon's trying to convince a federal judge to block the $125m settlement that'll let Google Books make out-of-print works available online. According to Amazon's newly-filed brief, allowing the settlement will essentially force copyright holders into allowing Google to scan in and sell their works whether they want to or not -- a thorny area of the law Amazon's gotten pretty familiar with as it builds out the Kindle library. Of course, since the actual settlement is between Google and those very same authors and publishers, it certainly seems like Amazon is crying crocodile tears here -- according to our old friend Paul Aiken of the Authors Guild, "Amazon apparently fears Google could upend its plans" to make the Kindle the dominant ebook platform. Heady stuff -- and with more briefs against the settlement due in the next few days from heavy hitters like Sony, Yahoo and Microsoft, things seem like they're building to fever pitch. We'll keep you updated.
