We can assign DOI identifiers for scientific institutions, higher education institutions and libraries, journals, and individual publications.
Official partnership – a key to success!
DOI or Digital Object Identifier is a unique numerical index designed for more convenient and quicker search and identification of journals, their issues, articles, and other types of research materials. It consists of a prefix and a suffix. The prefix identifies the publisher or the person who generated the DOI. The suffix is associated with an individual publication and is unique.
Only 11 companies around the world have the right to assign DOIs. The most popular of them is Crossref. Unlike others, the organisation has no regional restrictions. Scientific Publications, as an official sponsor of Crossref, can generate and assign an international DOI.
