You may want to buy the Picard's series of books, which cover significant parts of the beads made in the "hey-days" of the Venetian and Czech trade bead era. They can be purchased on their web site.

While it's always nice to find the exact bead on a web site, there were probably hundreds of thousands of patterns produced and there isn't a single source that documents all of them. So your "beaducation" should include handling lots of beads and learning to recognize the old ones. This forum continually updates people on new reproductions - it is a constant learning process - and they are getting harder to identify.

Welcome to the wide, wide world of bead collecting!
