I checked out these two great decorating books from the library:
My kind of decorating.
For those of us in the mid-century ranch family that have no idea how to keep the look authentic. Some are a little too modern, but the author gives great advice on decorating and landscaping in a way that is current, but also fits the era of the house itself. Call me a snob, but if a house is very obviously specific to a certain era (like mine, for instance), I prefer any remodeling keep with the style of that era. One could make it more current without losing authenticity. This book has some great ideas along those lines.
