If you want to publish an article or a book or chapter and your publisher does not assign a DOI identifier to your work, you can use the library's services.
On the website of the university library knihovna.tul.cz, in the Science Support section in the DOI section, you will find a form for assigning a DOI identifier.
Just fill out the form and librarian will contact you.
DOI allocation is charged.
The price for DOI is always paid by your faculty.
