For backpackers, cost-conscious families, first-time or seasoned travellers, these guides, updated annually, contain listings covering both cities and countryside, plus information on culture, history and people. Features include rail, city and regional maps, advice on work, study, hiking and biking, nightlife and even shopping tips. The researchers are all Harvard-Radcliffe students. They have to "make it on their own" - they have no expense accounts, no free hotel rooms and they travel on budgets as limited as do the people the books are aimed at.
