My favourite resource is Glass Beads from Early Anglo-Saxon Graves by Birte Brugmann. I can't say enough good things about this book. I will admit though, in my impatience to just start creating, I skipped the text and went straight for the pictures and I still haven't made it back to reading it yet. I like this book because the images included are actual photographs of the beads.
Another great resource is Trade Beads and Bead Trade in Scandinavia ca. 800-1000 A.D. by Johan Callmer. As far as I know, this one is out of print, but you may get lucky and find it somewhere or you can Inter-Library-Loan it. All plates are unfortunately drawings of the beads (not photos), but the sheer number of beads included makes it an invaluable resource.
