By European standards, Chicago is still a new city. But it's old enough to have lost many of its iconic buildings and features.

David Witter's book, "Oldest Chicago," looks at the noteworthy landmarks and businesses from Chicago's past that are still standing today, surviving decades, and even centuries, of progress and development.

Join Witter for a discussion of his work at 7 p.m. March 20 at the Sulzer Regional Library.
