News headlines are available to the right of subject headings. Advertising on the home page is limited and unobtrusive, and on other pages is generally restricted to a banner advertisement top and bottom. There is only one search interface. The search bar is also usefully made available at the bottom of the results display page. Navigation Fairly straightforward.
Links are primarily textual and therefore easy to identify and navigate.
Links back to the home page, e-mail and help features are usefully placed at the top and bottom of pages, including results pages. The directory structure is clearly indicated as you trawl down through the sub-categories with links back up through the hierarchy. Help Feature Multiple links on the main help page. Search help is not extensive but does include examples and achieves an acceptable level of clarity. Response Time Good.
