Transactions is a section in the print journal Leonardo that publishes fully refereed papers in a fast track to disseminating key new results, ideas and developments in practice.
Papers are solicited under the stated aims and scope of Leonardo, but are restricted to two pages of published material. A fast referee process is employed in which the result is restricted to "accept" or "reject" a submission. If a submission is rejected, the submission of a revised version will be treated as a new paper.
The announcement of results or developments in a Transactions paper will not exclude that work from subsequent publication as a full Leonardo paper. However, any such submission will be considered by Leonardo, in the normal way, as a new paper.
Papers that are correctly formatted and still under review can, with the author's permission, be published in Research Announcements. Open access is provided to these papers.
Papers should be submitted electronically in final camera ready form according to Leonardo's editorial guidelines and the Transactions guidelines. Incorrectly formatted papers will be rejected without review.
