Archie's fake ID says "Wilbur Wilkins" - a comic title that Archie Comics published from 1944-66.
The title shares it's name with the movie from the 1976 (and 2014 remake) "The Town That Dreaded Sundown" that shared many similarities to this arc including mysterious killings and a killer in a hood.
The fight scene between Archie's crew, the Red Circle, and the Southside Serpents is a tribute to the gang fight from The Outsiders (1983).
The librarian's name is "Mrs. Paroo." Marian Paroo, the leading lady in the classic musical "The Music Man," works as a librarian.
