Hope to pick the collective brains of the groups here. Does anyone have any suggestions for materiel to review that will detail how to recognize architectural styles of houses, and the common characteristics thereof? EG: "Ranch", "Victorian", ect...? Obviously my preference would be for some free, online training. I'd like to bring this training to the company next shift. But if anyone has some really top notch stuff they can recommend that is a commercial product, I'd look into that too.
