Look to the West - actually not a reference to part of the lyrics in the Led Zeppelin song Stairway to Heaven (see the opening words on the main page). Thande acknowledged this already in the early days of the LTTW timeline. Despite the name not being an intentional reference to the lyrics, he adopted that bit as an unofficial intro because he quite liked the thought.
Interlogue: Perfidious Albion - based on the well-known pejorative idiom.
Chapter #153: Sittin’ on Top of the World - reference to the interwar era Al Jolson song.
Chapter #186: Pee Dee Shames - a phonetic pun on P. D. James, the pen name of British crime writer Phyllis Dorothy James.
Chapter #201: Spoilers - probably a follow-up reference to Silence in the Library, as one of the characters in the episode uses the word as a catchphrase.
Chapter #206: Nation Shall Speak Boasts Unto Nation - a paraphrase of the BBC motto, "Nation Shall Speak Peace Unto Nation".
Chapter #215: A Girdle ‘Round The World In Forty Minutes - reference to the Jules Verne novel, Around the World in Eighty Days.
Chapter #218: Enter the Dragon - reference to the Bruce Lee martial arts film.
Chapter #223: Cookeing the Books - pun on the idiom “cooking the books” (i.e. falsifying bills and invoices).
