When Abebooks' Richard Davies sent word that the site's top-selling book of last week was Dr. Seuss's THE CAT IN THE HAT, a little investigating turned up the probable reason: the book will be 50 years old on March 2, and to mark the occasion, the National Education Association is conducting a 'National Read Aloud' of the book, known as Project 236 (in honor of the number of words used in the book) across schools, libraries, and book clubs. The event will take place on the 2nd at 2:36 PM Eastern Standard Time. Random House Children's has also set up a spiffy site to commemorate the book's birthday and for more information on the event (although there are only so many ways to hear "Happy Birthday" before it sticks in your brain for an indefinite period of time...)
