In my town there's nothing much about samurai history, so I have to order books from England and basically most of them are written by Turnbull
Turnbull is widespread, but he's not an author I would recommend for serious study.
Try Karl Friday, George Sansom, Anthony Bryant (who can be found posting on another samurai-related forum) or Mary Elizabeth Berry.
Here is Tony Bryant's site: Sengoku Daimyo homepage
