Original papers
An original paper is only the first-time publication of original research results in a way that allows the research to be repeated, and the findings checked. As a rule, it follows the IMRAD (Introduction, Methods, Results and Discussion) scheme for experimental research, or it is organised in a descriptive way for descriptive scientific areas. The paper must be published in a journal with a peer-review system of accepting articles and must be peer-reviewed. The peer-review system must be evident from the instructions for authors.
Review Article
A review article is an overview of the latest works in a specific subject area, the works of an individual researcher or a group of researchers with the purpose of summarising, analysing, evaluating or synthesising the information that has already been published. A review article brings new syntheses, which also include the results of the author's own research. The review article must be published in a scientific journal with a peer-review system of accepting articles and must be peer-reviewed. The peer-review system must be evident from the instructions for authors.
Short communications
A short communication is an original article, in which some of the elements of the IMRAD scheme may be omitted. It briefly summarises the findings of a completed original research work or a research work in progress. Also included in this category are mini reviews and preliminary publications, if they have the characteristics of a short article.
