SPRINGFIELD, ILL. (AP) -- Two pages of a school notebook from Abraham Lincoln's teen years have been reunited after 145 years.
Researchers for the Papers of Abraham Lincoln have electronically matched two pieces of a page from Lincoln's arithmetic copybook.
The book is from the 1820s. It's the oldest known original Lincoln document.
One part of the page is at the University of Chicago.
The other is at Brown University in Providence, R.I.
The arithmetic copybook page includes math problems on one side and a series of questions and answers on the other.
Lincoln's stepmother gave the book to law partner William Herndon after the 16th president's death.
Ten pages are known to have survived.
