Look It Up is a utility to search for terms on multiple web sites at once. It helps you find research sites based on Types e.g. Dictionary or Images. Once you choose a Type, you are presented with a range of Sources (pre-defined web sites that support keyword searching). Each Source appears in a separate tab (you can have as many of these Source tabs as you want). Enter the terms you want to look up and Look It Up will look up the search results of all Source web sites simultaneously. You can even define your own Source types!
Once you find your results you can have Look It Up speak the text of the web page to you, highlighting the text as it reads it.
Default Source Types include: Almanac, Biography, Dictionary, Encyclopaedia, Entertainment, Images, Legal, Library, Literary, Maps, Medical, News, Quotations, Search, Technology, Thesaurus, Translation, Video, Weather and Wiki. There are over 250 Sources included.
