On the Anglo-Saxon Age
Blair, John. The Anglo-Saxon Age. Oxford: Oxford University Press, 2000. pp. 90. Paperback.
This is a decent starting point for early medieval Britain, and I think any faults I have with it are more a problem of source base than the text itself. I would have liked more detail, but when annals and archeology is all you have to work with, you can’t get much more than a broad outline. I’m sure there are better texts, but this is probably one of the shortest.
