Apple acquired BookLamp startup for $10-15 million earlier this year (Update: confirmed)

Apple acquired a company called BookLamp earlier this year for somewhere between $10-15 million, according to information uncovered by TechCrunch.

The Idaho-based startup created what was referred to as “Pandora for books,” including a system known as the Book Genome Project that could recommend books based on analysis of the text and previous ratings of other books by users (very similar to Pandora’s Music Genome Project, which does the same thing for musical analysis).

According to TechCrunch, several of BookLamp’s employees have moved to California since the startup announced that it was shutting down in April. It seems that at that time, both Apple and Amazon were expressing interest in acquiring the company. Amazon eventually backed off and bought GoodReads instead, leaving BookLamp for Apple.

While BookLamp still has its Idaho office, it has since opened a new Cupertino office, though TechCrunch’s sources claim that no employees actually work in either building. Instead, all of the employees are now at Apple, likely working on an improved search or recommendation engine for Apple’s own iBooks service.

Update: Apple has confirmed to Re/code that it acquired BookLamp.
