The Bay Psalm Book, the first book published in America, became the most expensive book ever sold at auction last week.

One of only 11 known to exist today, the book brought $14,165,000 at Sotheby's on Tuesday. It was published in 1640 by Puritan settlers in Cambridge, MA.

The buyer was American businessman David M. Rubenstein, of Washington-based investment firm the Carlyle Group, He plans to loan the book to various libraries.

The little book of psalms surpassed the previous book record of $11.54 million paid in 2010 for a copy of John James Audubon’s “Birds of America.”
