Units are broken down into several topics, each of up to several pages, which link students directly to relevant library resources. The user has full access to the whole library, complete with the more traditional search engine and drill-down navigation.
In this way, the guide acts as a sort of librarian, pointing users to the right sections and giving examples of specific relevant resources whilst giving them free rein to research the whole collection.
Each unit also includes a dozen or so multiple-choice questions intended for self-testing, to reinforce the key points covered and flesh out the theory with examples.
