Digital libraries, databases, archives, etc. enable Internet users to find a variety of research materials. DOI is a tool that simplifies the search and use of such materials.

With the development of information technology, scientific journals have their own websites where articles can be found. Scientific databases index research, and electronic libraries and archives contain a large amount of material that allows researchers and students to find the information they need.
What is a DOI?
DOI – Digital Object Identifier – is a unique number assigned to an electronic object on the global Internet, which greatly facilitates its search and use. Such objects can be digital, physical or abstract. In other words, a DOI is a reference to a specific object.

A DOI is a unique number consisting of a prefix and a suffix, which can include both numbers (always starting with 10) and letters. The prefix identifies the publisher, and the suffix is a unique object number. The prefix is a set of numbers that is assigned to the publisher after concluding an agreement with the registrar. The suffix is assigned by the publisher, including the journal code, volume, and article number. Numbers and letters of the Latin alphabet can be used in the suffix. It is important to note that a publisher can have an infinite number of materials, but each of them must have a unique suffix.
Advantages of publishing with DOI
- Citation. The presence of a DOI digital identifier provides researchers with easier citation in scientific papers and inclusion in the list of references. This helps to increase the author's citation level and, accordingly, increases the Hirsch index.
- Guaranteed safety. Unlike websites or digital libraries, digital objects with an identifier will always be available at the place of their registration.
- Universality. The DOI identifier is universal and recognised by the world community, as all major publishers have appreciated its convenience and security.
- Databases. A publication that has received a digital identifier immediately becomes available for citation on the Crossref website and in various global scientific databases.
Today, DOI has become one of the key elements of scientific communication and knowledge dissemination. It provides a reliable and standardised way of identifying, accessing and citing digital resources, ensuring their long-term availability and facilitating accurate referencing in academic and professional circles.
All scientific publications supported by Scientific Publications receive a DOI identifier. We provide separate services for generating and assigning a DOI. Fill out an application on the website, and our manager will contact you within a business day.
