Oxford Reference Online is a comprehensive resource that contains over 120 dictionaries and subject reference books published by Oxford University Press.
Oxford Reference Online allows you to search or browse (via an A to Z list) all 120+ titles or any individual title.
Upon viewing an entry you have additional functionality right at your finger tips.
For example, the button allows you to select a word or group of words within an entry and search across the entire database for other reference sources that contain these words.
New resources are added every quarter. A recent addition includes the Visual English Dictionary, which contains over 6,000 illustrations!
