Working Papers

The main internal publications of the DTU are Working Papers, Technical Releases and Research Notes. Most DTU publications are available here for download in a number of formats and hard copies of Working Papers are available free on request to the DTU. Technical Releases will also be sent free on request but only to addressees in developing countries.

Working Papers are used for descriptions of research findings and are written for a "professional" audience: comments are welcome. In some cases revised versions are subsequently published in outside journals.
