The three sites are the only ones I reccomend at this time for those looking to read a bit about Ninjutsu history. There may be others, but I can't think of them at this time.
Of course I reccomend my own article on Koga ryu ninjutsu.

And the following is the best resource I have ever seen on Fujita Seiko- last person to claim to be the soke of the Koga ryu in Japan.

And if you want a non-practcioner's outlook, but well done with good sources try Alexei Gorbaylov's article on the realities of what the ninja were.

Again, there may be more. Let me if you know of any. I will be sure to let you know what I think.
