Information is also published in the form of articles in scientific and technical journals, and as oral papers at conferences, workshops and similar meetings. These documents are published through a variety of sources, including EUR-OP (the Office of Official Publications), individual RTD programmes and commercial publishers. This section of the journal provides abstracts and bibliographic details for these publications. Where a document is published originally in a language other than English, the abstract is given in both the original language and English (in italics).
