Letters are limited to four journal pages, should be particularly interesting and timely, and usually are expected to be followed by a more detailed article at a later time.
Reviews cover a broad category of research, including results from various research groups.
The journal contains a subject and author index in the December issues. A category of article, the 'special topic', has been introduced to cover, for example, results from scientific working groups supporting programme planning, or a summary of a limited body of research. NF also publishes the World Survey of Activities in Controlled Fusion Research. The Board of Editors is responsible for management advice from the scientific community.
