There are a few books that have had a great influence on the second time round Anglo Saxon England. I have listed the few most important ones here.
Britain after Rome by Robin Freeman
Robin Fleming very consciously takes a less traditional approach to the Anglo Saxon period than most; there's relatively little about political history, though there is some, and it might well be argued that this is a more balanced approach, and much less focus on what the textual history tells us.
I really enjoyed it; it has a distinct flavour which is at times challenging and invigorating, and at others mildly annoying - it's a book I think that makes you react. I loved the real insights that the focus on archaeological evidence gave into the lives of everyone, not just the social winners; though at the same time, there's sometimes too much of the archaeology - the detail can get int he way, and the frustrating thing is that there are often no answers, of course, to the story burials tell - for example the woman buried on top of another, probably buried alive half crushed by a big stone.
The bit I found least convincing was the idea that much of the early migration was peaceful, migrants fitting into a kind of egalitarian community building. There's no doubt that generally the author's vision of the real world of the migrations is much more convincing than the older, traditional view of the migrations would have it, but I help but feel it must have been accompanied, even in the early years, by a substantial degree of violence.
The last chapter and the attempt to paint a picture of what life must have been like is brilliant, and I'd say this book, accompanies by others, is essential reading for anyone wanting to understand the Anglo Saxon age.
The Anglo Saxon World by N. Higham
This is sumptuous beyond measure - beautifully produced, highly illustrated, and it is a job. The information is presented very clearly, with great balance and clarity. There are excellent sections on specific topics. OK, it's a textbook; but it's a thing of beauty.
Anglo Saxon England by Frank Stenton
The definitive textbook originally produced in 1943, and a work of brilliance - still the most comprehensive. You have to watch it a bit; there is the odd thing in here which has now been discredited, for the most part it's the best reference you can have.
