Amy Poehler mentions, in an interview, that they just made up their anti-library stance in order to make a joke. But it turns out that they found many government officials actually shared those sentiments.
How much does Parks and Recreation hate the library?
The library represents that branch of government that’s like the smart kid—the teacher’s favorite. And the library always wins. They get whatever they want. Everybody loves them—nobody can say anything. People who work in the library think they are so much better than everyone else. And what’s really funny is we’ve been doing Q&A’s about our show, and people from local governments have said, “You guys nailed it about the library.” We were just making it up as a joke on the show, but I guess everyone hates the library.
