EBSCO has given us a new way of looking at our search results. Instead of merely producing a list of results, you will see them in clusters by topic; the circles represent categories, the squares actual links to articles.
Let's say you are doing a paper on Jane Austen. Your results will now include circles for biographies, criticism, film adaptations, Pride & Prejudice, etc. If you click on the Criticism circle, you will see more circles (more categories within criticism) and squares. If you run your mouse over a square, a summary of the article appears. If you clink on the square, the article will open in the panel on the right. You can save, email, print the article or add it to the folder.
Compare the Visual Search to the "Narrow Results by Subject:" that is available in the Basic or Advanced Searches and you will see why this is a valuable new tool to aid you in your research.
For more information about Visual Search, there is a tutorial with audio (2.20 minutes runtime) which will introduce you to this new feature of EBSCOhost.
