Within each book, locations are not repeated. But locations "start over" with each book. Places within places ALREADY NAMED WITHIN EACH BOOK (i.e. rooms, buildings, stores)are not included. For example, Flourish and Blotts is not included when "Diagon Alley" has already been visited, but Hogsmeade Station is included when the village of Hogsmeade has not yet been mentioned. "Hogwarts" refers to every place within the castle itself, not all places on Hogwarts grounds. Places/things without a permanent location are not included (i.e. The Knight Bus). Except for people's houses, places without official names are not included. Locations are categorized as places (spots that have names, but do not fit the other two categories, such as villages, streets, and forests), buildings (places confined within the space of one structure), and houses (places where people live).
