The complete  reference should include as appropriate, the following: name of the author, title of the work, date and  place of publication, date of creation, address of publication on the internet, number, volume and  other information that allows the origin to be easily identified.

When making use of the  Results , the contractor must declare that they have been produced under a  contract with the contracting authority and that the opinions expressed are those of the contractor  only and do not represent the contracting authority’s official position.
