Wartime West Sussex 1939-45. I love these kind of websites, where I get lost looking at diaries, photos, and all sorts of fascinating historical tidbits that help me appreciate and better visualize what life was like back then.
The D-Day, air raids, home guard, and many other sections are fascinating. Neat audio interviews abound. From their website: "These pages have over 700 digitised sources about life in West Sussex during World War II. They include photos, official leaflets, book extracts, newspaper articles, letters, diaries, original records and recorded memories." They also have a section on Victorian life, but it pales in comparison.
