This paper describes the construction of Victorian windows in residential buildings, primarily in the northeastern United States. The period studied is approximately 1860 to 1900, although some earlier examples are discussed. Along with window types, information about window sizes, shapes and number of lights is included. Related data about typical window shades, blinds, screens, storm sash and hardware are considered. It is the intention of this text to give the reader, through the historic typology, a feeling for the importance of windows in historic buildings and a listing of some primary resources relevant to the process of historical investigation. Resources used in this study are limited to nineteenth century pattern books, handbooks and trade literature. Correlation to recorded structures is not included in the scope of this study. Some gaps in information may be evident, due-to availability of primary informational sources.
