For each street, the following information is given:
- Street name in full
- Route of the street, described in the direction of increasing house numbers, including any portion in another municipality where the street keeps the same name. Directions (N, E, S, W, NE, SE, SW, NW) are relative to other major streets in the area; “north” is usually closer to true north-northeast.
- Indication if the street is “private”, not on town-owned property
- Neighborhood(s) and any other municipality the street passes through. Neighborhood boundaries are shown on this map, which is based on the map in Hartley's History, with some changes reflecting street development since 1959.
- A date for when the street first existed. For most residential streets, this is the date of the plat, or subdivision map, that first showed the streets. For the longer, older streets, this is the date of the first map that showed, but not named the street: the 1852 Whiteford map of New Haven County, the 1856 H. & C.T. Smith county map, or the 1868 map of Hamden in the F. W. Beers county atlas. For a few streets, the date is of its first appearance in the city directory, or of the oldest house on it according to tax assessment records.
- Information about the street name. It is usually not certain that the street was named for that reason. In some cases there is more than one possibility, but in others fairly convincing evidence is given for the one derivation. References to some sources are given:
