When you publish UT-related work, such as your dissertation, in-house, you have to request an International Standard Book Number (ISBN). You will be charged 43 Euros for an ISBN, which you will receive by email within three working days. In case of a dissertation you will also receive a persistent identifier, a DOI (Digital Object Identifier). A DOI guarantees sustainable access to your work, even if the URL changes.
An ISBN as well as a DOI are related to the University of Twente as publisher. For applying an ISBN and DOI, please use this application form.
