Different types of publications

Generally, scientific articles are the most dominant form of scientific publication, even if this varies between different fields.

There are different types of scientific articles, here we present some of the most common.

Original articles

Original articles, research articles, empirical articles and research papers are empirical studies showing the results of new research for the first time.

Review articles

Review articles do not show the results of a study of their own. A review article describes, analyses, summarises, and assesses published research within a limited field of research. A systematic review is characterized by the fact that it has been carried out based on a certain methodology with the aim of compiling all available research within a subject area. All steps in the process are carefully documented.

Examples of review articles are literature reviews, systematic reviews, meta-analysis, integrative reviews, scoping reviews, etc.

In the article A typology of reviews: an analysis of 14 review types and associated methodologies (external link), the authors describe what characterizes 14 different types of review articles. The article Meeting the review family: exploring review types and associated information retrieval requirements (external link) also describes different types of review articles. You can also learn more about different types of review articles in books about research methodology.

Although review articles summarise individual studies and can therefore be considered to have a greater scientific value, these types of articles also need to be reviewed and evaluated based on how the review was conducted.

Theoretical articles

Theoretical articles discuss and develop theories within a subject. These are, however, not as common as original articles and review articles.

Versions of articles

Different versions of articles exist, because they can be made available online at different periods of time in the publication process. There are several different labels for this depending on where in the process the article happens to be. Furthermore, different journals sometimes use different names for the same type of material.

Preprint

Preprints are articles that have not yet been peer reviewed (reviewed by subject experts). Another name is author original manuscript.

Postprint

Postprints are articles that have been peer reviewed but have not yet been given their graphic form. Sometimes they can be called author manuscripts, accepted articles, or accelerated article preview.

Published ahead of print

Published ahead of print are articles that have been peer reviewed, they have been given their graphic form and they have been published on the web but the journal issue in which the article will be published has not yet been decided. They can also be called, for example, EarlyCite articles, article in progress, article in press, online ahead of print, early view and online first.

There are various types of conference proceedings, such as papers, abstracts, and posters. The common denominator is that they are all presented at a conference. Frequently, the papers presented at the conference are published in a collection publication, so-called proceedings. Not all conferences have a peer review process, which influences the conference papers’ scientific quality.

Conference proceedings can also vary in their impact within different fields of research. In areas where the rate of publication is high, computer science, for example, conference publications are one of the most important ways to disseminate research findings.

A thesis is a scientific work that is produced within a doctoral programme. There are two types of theses, doctoral theses and licentiate theses. A thesis is usually published in the form of a book.

In contrast to other scientific material, a research report or scientific report is usually not reviewed by other researchers before it is published. Usually, reports are published in a report series from various university colleges and universities. Sometimes they are produced to form a basis for decisions by various official agencies.

Academic non-fiction (a type of book) differs within various subject areas. For example, within the humanities and law, it is more common for researchers to present their research either as a book or as a chapter in a book, in a so-called anthology. An anthology has chapters written by various researchers and an editor who compiles the chapters. This entails that an anthology is often thought to have greater impact as a source compared to a book by one single author, as the contributions have been reviewed by the editor. Academic non-fiction contains scientific investigations, research surveys or theoretical perspectives.

Scholarly books sometimes, but not always, have a peer review procedure similar to that of scholarly articles. Instead, there are other quality signs you can look out for:

• Is the book's author a researcher working at a college or university?
• Which publisher has published the book? Is the publisher scientific? To review the publisher, you can use the Norwegian list (external link) and the Finnish list (external link).
• What information is there about the review process of the book's content? Read the book's preface and introduction as well as on the publisher's website to find out more.
• Are there references in the book to other scientific publications?
