This appears to be a recurring event or program title (e.g., 'Thursday Stories') at the venue rather than an actual performer or artist name. The format 'THURSDAY STORIES W/THE ECLECTIC LIBRARIAN (18)' indicates a weekly program series with episode numbering, consistent with in-house programming at a children's museum. No evidence found of 'The Eclectic Librarian' as a touring performer or established artist with a public presence.
