CHICAGO (WBBM NEWSRADIO) -- There are overdue library books, and then there's this.

Over a century after it was checked out, an overdue library book has been returned to Lakeview High School on Chicago's North Side.

"The Autobiography of Benjamin Franklin" was returned to Lakeview High School this week.  When was it checked out?

February 9, 1913 - 105 years ago; World War I was 18 months in the future.

It didn't return until this week, when it was mailed to the school from an estate trustee in Tucson, Arizona.  A note was left inside.

"This book was left by an elderly friend who has passed away. After more than a century, I thought you might like to have it back," the note read.

John Talley is the new media coordinator at Lakeview High School.  He said there are a bunch of one word notes in the margins. And although he's not sure what the notes mean, he suspects whoever had the book might have used it for a research paper.

The book will go into the school's historical archive.
