Goodreads Librarians Group discussion

Hello! I noticed that in my copy of the book the first copyright/publication date is listed as 1919, as opposed to the 1946 listed.
Furthermore, in the "To the Booksellers" note, Morley write that this book is written for "saying something further of the adventures of Roger Mifflin." That combined with the same cast of main characters, and same concept (bookselling), I think it would make sense to list this as a sequel of Parnassus on Wheels. (Parnassus #2, Parnassus on Wheels #2?)

WorldCat has 1918, so I've changed it to that. Publishers are often out when publications happen near the New Year.

Leaving for another Librarian to do the series addition.
