I have authored research papers from 2008 in the field of biology, but there are no digital versions available. Is there any way to obtain a DOI for these articles? If so, what steps should I take to register them for a DOI?
The articles were published by my university's periodical, and I am currently unable to contact them because there is a war going on in my country. (I am from Ukraine.) However, I have the titles of the articles. Is it possible to obtain a DOI for them using just the titles, or does it have to be done exclusively through the university?
