Miss Campbell ("Willy" to her friends, though Bosley was the first person Tiffany had ever heard use the nickname) was a reference librarian at Tiffany's former university.
She was very direct in approaching Bosley, taking an immediate interest in him. When he asked her for a drink she immediately suggested that Carrington's Pub was a "swinging place". Bosley kissed her cheek.
Tiffany suggested that the relationship was getting serious, and Bosley's only response was "So is this case." He later described her as "a very amorous librarian."
