TechCrunch has learned that Apple has made another acquisition, one that it is using to boost its e-books effort and "beat Amazon at its own game." It has bought BookLamp, a startup based out of Boise, Idaho, that developed big data-style book analytics services. A second source says Apple bought BookLamp's employees and technology for a price that was "higher than $10 million, and lower than $15 million."  BookLamp's most well-known product was the Book Genome Project, a platform that let users find suggestions for books to read based on natural language analysis of other titles. BookLamp's tech and talent could help Apple improve its iBooks service with better recommendations, search, and categorization.
