This past Monday, Amulet Books published Dog Days , the fourth volume in the popular Diary of a Wimpy Kid series, written and illustrated by Jeff Kinney. Because of the series' popularity, Amulet published the book with a four million copy first printing. At our library, we purchased 20 copies of Dog Days . We put the books out at 3:15 p.m. on Monday, the day Dog Days was published, and by 4:30 p.m. that same day, all 20 copies were checked out and we had a waiting list of 15 people. Because the book is a quick read, however, we expect those on the waiting list will get to read Dog Days before too long!
