By the end of the year, all 26 Nate the Great books will be available as digital books. Forty years ago, Marjorie Weinman Sharmat began the series of books about a boy detective.

Here’s more from the release: “In addition to the eBook launch, a new Nate the Great chapter book titled Nate the Great, Where Are You? will be published in May 2014. This is the first new title in the series since Nate the Great and the Hungry Book Club in 2009, both co-authored with Mitchell Sharmat.”

The eBook launch begins on January 30th as Random House Children’s Books releases five books from the series: Nate the Great, Nate the Great and the Snowy Trail, Nate the Great and the Pillowcase, Nate the Great and the Monster Mess and Nate the Great and the Mushy Valentine.
