For over 50 years, Oxford`s Dictionary Department has been collecting, sourcing, researching, and authenticating quotations on an international scale. In doing so, it has created one of the richest language resources in use anywhere in the world today, and has developed the most thorough and reliable editorial procedures. For each newly discovered quotation, detailed follow-up research is carried out to verify its authenticity and to provide clear details of its context and background. Fully authenticated quotations are stored in a special electronic database, the major source of material for new Oxford quotation dictionaries and new editions of existing bestsellers. Clear information about the context of each quotation is readily available, and immediate access is provided to all the salient details of attribution and source. In addition, Oxford`s keyword indexes ensure that particular quotations can be instantly retrieved.
