Developed by Stephen Ives and Ken Burns, PBS's offers a Web site debuting to coincide with the documentary series _The West_, which began airing this week. This frames-based site is both textually and graphically rich. Its stated purpose is to explore "elements of Western history--profiles, documents, images." It includes a mini-guide to each episode, over 75 biographies, interactive timelines, maps, photographs and text documents (letters, legislation and judicial rulings). The only drawback is that the site is somewhat confusing to navigate. Users must follow site instructions carefully in order to navigate between the contents listing frame and the main frame.
