“Like millions of Americans, I grew up with ‘Peanuts.’ But I never outgrew it.”

So begins the foreword written by President Obama for the 25th volume of “The Complete Peanuts,” the latest in a series of hardcover books reprinting every daily and Sunday strip of the iconic series that appeared from 1950 to 2000. The volume, which is scheduled for release in May, covers Jan. 1, 1999, through Feb. 13, 2000, when the final “Peanuts” strip was published the day after the death of its creator, Charles M. Schulz.

“For decades, ‘Peanuts’ was our own daily security blanket,” President Obama writes in his introduction. “That’s what makes ‘Peanuts’ an American treasure.”

No one would agree with that assessment more than Gary Groth, the president and co-founder of Fantagraphics Books, which has been publishing “The Complete Peanuts” since 2004. Mr. Groth wanted to make sure this volume was special, beginning with the introduction — and who was going to write it.

“Obama was inevitably at the top of the list,” he said. “Let’s just reach for the stars. All he can do is say no.”
