I love the look of the new World Book Online sites. My favourite site is World Book Student mainly because it was the first site launched in Australia back in 2000. Over the last 15 years, the site has had many changes to keep up with changing technology, and has ways to make the information easy to find and explore.
During my training sessions with teachers, there are a lot of "ooh aah" from the audience. One of those features is the page showing all the Australian articles. Teachers say it's also one of the main reasons why they switch from other databases.
