Stoddard's Lectures are a series of books, compiled by author/lecturer John L. Stoddard, that Lewis Barnavelt discovers shortly after moving to his uncle's house in New Zebedee (The House with a Clock in its Walls, 18-9):
- Lewis initially reads volume 9, which he thinks smells like Old Spice talcum powder, on how nobles murdered Rizzio in front of Mary, Queen of Scots (House, 19).
- Lewis skips out trick-or-treating (and delays attending Mrs. Zimmermann's cider-and-doughnut party) to read "the exciting part" of one of Stoddard's books (House, 70).
- Lewis has read about the battles of the Spanish Armada in Stoddard's books (mentioned in both volumes 5 and 9) (House, 72).
- Later, after seeing a spectral vision of his deceased Aunt Mattie, Lewis retreats upstairs and reads volume 3, specifically Stoddard's "second lecture on China" (House, 119).
- Following a confrontation with Mrs. Izard, Lewis admits Stoddard "tells you all about Hands of Glory" (House, 174).
