I've always been pretty confused as to what the difference of perch-phaetons, coaches and other carriages, and also men's and women's clothings. SO I'm glad I read this book. It's really more of a reference book - which is why it's a must-have for GH fans - and it wasn't as entertaining, reading this chronologically. (The book kind of gets boring as it goes along). Still it's very useful book to help certain Georgett Heyer fans to better visualize the book they're reading. A good education on what it was really like in Regency times, and even interesting history lessons on the Who's Who in Regency era (whom GH almost always mentions in her novels).
