(Undated) -- Minnesota's rural libraries are finding playful ways to remain relevant. The Willmar Library hosts everything from Nerf wars, escape rooms, and teen lock-ins to a holiday-themed murder mystery party, an Iron Chef competition, karaoke singing, and a dance party. A Rochester librarian launched a true-crime discussion group and is offering speed friending, a version of speed dating. Librarians in small communities often have a lot of autonomy to bring new ideas to life and face less competition for people's attention.
