Henry Glassie is considered the father of the study of vernacular architecture. Having heard that his early books are tedious, detailed examinations of buildings, I am surprised at how casually written (no footnotes!) and broad this is. He argues that the definition of vernacular architecture should be expanded beyond "folk" housing, but the examples he includes hardly support his assertion. At one point he notes that industrial production exaggerates the characteristics of vernacular architecture. I hoped he would expand upon this observation, but ultimately he did not. Strangely, Glassie also attempts to formulate three historical periods of architecture in America in the second part of the book. It sounds like I didn't like reading this much, but what makes it a worthwhile read is the first half, in which he shares personal stories that demonstrate the ways in which houses have lived histories.
