If you're interested in seeing actual artifacts from William McKinley's Presidential office and his home this is the place to go. As a bonus, however the building that keeps the artifacts also hosts a museum of sorts for different periods of time.

The only thing I didn't like about the president William McKinley Presidential Library and Museum was the robotic figures of William McKinley and his wife Ida that were towards the back of the museum display. These robotic figures were timed to talk to observers of the museum display. If you weren't ready for it, it kind of catches you off guard, and you're not sure how to react At first.
