The 167-year-old papers represent a rare historical find. Lincoln scholars since have determined they are authentic.

Museum spokesman David Blanchett tells the Daily Herald that such a discovery as the one Spriegel made is usually the work of a research with years of experience.

As for Spriegel, an aspiring librarian, he tells the newspaper he can’t wait to tell his professors back at school about his experience.
