Assigning ISBN numbers to DTU publications

Both printed and electronic publications must have an ISBN number. There are no legal requirements that ISBN numbers must be assigned to publications published in Denmark. It is, however, DTU policy to do so.

ISBN accountable at departments and centers
There is no central DTU authority assigning ISBN numbers to DTU publications. This means that you need to e-mail the person responsible for assigning ISBN numbers at the relevant department or center. The e-mail must contain the correct title of the publication as well as author names.

The following types of DTU publications do NOT need an ISBN number:

• PhD theses.
• Reports if they are printed and issued only to a closed circle of people and are not made available to the public, neither in printed nor electronic form.
• Reports, which are circulated only to a limited group of people (i.e. 20 municipalities or 50 schools or the participants in a survey), neither in printed nor electronic form.
