The Genealogy In Time online newsletter has a three-part series of articles dealing with English Genealogy. It takes the unique approach of examining the types of genealogy records available by date.

It is an interesting approach and one that you could use in any context. Check out part 1 of the series at http://goo.gl/HCqFN
