We may be well into 2012, but Harvard's 375th Anniversary celebration is far from over. As part of the festivities, Harvard has announced the John Harvard Book Celebration, a series of lectures at Cambridge and Boston Public Libraries that are free and open to the public. The series formally began in January, but there's still plenty of time to catch some of the most exciting speakers between now and May, including Drew Faust and Steven Pinker. Finally, in honor of the 400 books famously donated by John Harvard to the nascent University's libraries in 1638, Harvard itself will donate—you guessed it—400 books to Boston and Cambridge libraries, which, in case you were curious, constitutes approximately .0000002 percent of Harvard's own 16.6 million-volume collection.
