I want to know the answer to the following question:
What state operates the Abraham Lincoln Presidential Library?
All the background I'm provided with is that "Libraries and museums have been established for other presidents, but they are not part of the NARA presidential library system, and are operated by private foundations, historical societies, or state governments, including the Abraham Lincoln, Rutherford B. Hayes, William McKinley, Woodrow Wilson and Calvin Coolidge libraries.". Is that enough to answer the question?
Answer: no
