John Davies sifts through the schedules for academic viewing (times pm unless stated).

Pick of the week.

The BBC's "History 2000" programmes are a mixed bunch; Monday's Breaking the Seal does not seem to make the most of its material. But a new series on genealogy, Bloodties (Saturday 7.35 BBC2), looks more promising: it follows various people's quests for their ancestry. The main story in this first programme is that of the descendants of Labour Party pioneer Ben Tillett, some of whose papers have ended up in Warwick University's archives.
