The former president and first lady read to children at the presidential center library on opening day Friday.
The Obamas read to children and parents at the library at the presidential center Friday.
Barack and Michelle Obama read "Where the Wild Things Are" to a crowd of students, staff and parents from Ray Elementary school.
Reading the Maurice Sendak book has become a tradition for the Obamas.
They read the book to children while in the White House, and Mrs. Obama narrated a special 60th anniversary unabridged audiobook edition.
The Obamas hope the book inspires young people to dream bigger, explore new possibilities, and recognize their own potential to lead and create change in their communities.
"This is your library. When I was your age, I loved books; I loved coming to libraries. Although sometimes the librarians said, 'shhh' because I was too loud," Barack Obama said.
After the interactive reading, Obama's parting message was encouraging the students to come back.
"When you read 'Just Like Max,' you bring the world to you; you can see everything and learn everything," Barack Obama said. "I want you guys to keep reading and the library is a great place to do that."
Reading Rainbow icon LeVar Burton also read to the children.
Some Ray parents volunteered for this special field trip.
"I was really excited to see my president, Barack Obama, Michelle Obama. They were everything and more I would have wished for," Daunte Henderson said.
"I am so pleased ... what a gift to us and our children, and something I will cherish for a long time," Benjamin Walker said.
Now 10-year-old August DuBois met Obama when he was in office.
"Last time I saw him when I was 1 I pinched his nose. I think I have a more pleasant experience with him this time," DuBois said.
The kids went to playground after the special reading.
Then the library was open to the public with people standing in line to get in and to check out books and get their very own Chicago Public Library card from the Obama branch.
