|Subject: Re: B&B Guide for Western European Countries?|
You don't mention whether you have checked out regular guidebooks - Rick Steves, Lonely Planet, Rough Guides, Let's Go, etc. These cover B&B's as well as other kinds of accommodation.
If you are looking for more upscale B&B's, you might try these authors: Alistair Sawday, Karen Brown, Sandra A. Gustafson/ Sandra Wood (Cheap Sleeps). Fodor's has a guide to B&B's.
Here's an article on guidebooks: http://tinyurl.com/e4d3o
In addition, there is alternative accommodation such as convents, youth hostels (not just for youth!), depending on your reason for preferring B&B's - cost, style, location, etc. See TheTravelzine's link page: http://groups.yahoo.com/group/TheTravelzine/links
There are also foreign language guidebooks - for example, Routard. http://www.routard.com/
