Hi Bugglie,
i do own the book on Bulbophyllums and their Allies by Emily Siegerist. i find that it gives you at least a rough idea on the cultural requirements of various Bulbophyllums (which is a good start) but if you want pictures, its much better to look it up on the net. I find that by cross referencing with the book and online sources like Orchid Board and the link below,
Jay's Internet Orchid Species Photo Encyclopedia Bulb - Bz
you will be able to piece together a much bigger picture of how do you go about taking care of different bulbophyllums.
Cheers and happy growing,
Freddie
