When shopping for a new plant, a really useful book, and sized right to carry along, is _The Taylor Guide to Orchids_.
While it doesn't contain detailed information, it has the essentials in choosing a plant for *my* climate: temperature preference, light preference, easy/hard to grow, and (very critical) whether or not it is fragrant. And there are photos.
Sadly, this little book runs about $28, but can be found at used-book stores, etc.
