helps you plan your weekend by previewing daytime programmes of special interest from the Open University. This week there's a clip from Two Yorkshire Families showing the local historian at work piecing together the story of two West Riding families from letters, diaries, paintings and estate records. There's also a trip to Pompeii to study Roman Interior Decorations, well preserved by layers of ash after the eruption of Vesuvius in AD79, and a discussion of business attitudes to education in The National Interest.
