Here’s another library mentioned in the Archie universe: this one is the Greendale Public Library, from the Sabrina story “Equal Rites” (first published in Archie Giant Series Magazine 243 (January 1976), but read by me in Betty and Veronica Double Digest 94 (February 2001). Greendale is near Riverdale, where Archie and the gang live.
In this story Sabrina and the others are decorating a Christmas tree when her boyfriend, Harvey Kinkle, drops by and thinks that some magic he saw was actually caused by a poltergeist. He rushes away to look up how to rid a house of a poltergeist.
“Equal Rites” was written by George Gladir, pencilled by Stan Goldberg, inked by Rudy Lapick, coloured by Barry Grossman and lettered by Bill Yoshida. It is copyright by Archie Comics.
