Let's face it - it's an old book. While the information given is still correct, it's presented in an old-fashioned, dry way. Cattleya culture is explained extensively and the culture of other species is derived from it. So to find one piece of information, you have to read most of the book... Moreover, most of the pictures are black and white, and while there are some color photos, their quality is often questionable. And the title is misleading: it's not written especially for home growers. It's written for all orchid hobbyists, most of them having greenhouses.
All in all, it's just gotten to be an old book.
