[Regia-NA] In need of book reviews

[list-regia-na@lig.net]

Hello All

Second year of university, and I have discovered the magic of inter library 
loan. I have a couple books on order (Dominic Tweedle's 'The Anglian Helm From 
Coppergate) and was thinking of ordering two more: The Anglo-Saxon Shield 
by I.P. Stephenson and Early Anglo-Saxon Shields by Tania Dickinson, Heinrich 
Harke. Are these worthwhile? What timeframes do they cover?

Also, I recently heard that tenth and eleventh century shield bosses found in 
Ireland display noticably different characteristics than those from elsewhere 
in Europe, but whatever I was reading did not go into any detail. Anyone know 
of a book which may touch on this subject? 

Regards,

~Wil
