A scientific journal is a periodical publication intended to further the progress of science, usually by reporting new research. Most journals are highly specialized, although some of the oldest journals such as Nature publish articles and scientific papers across a wide range of scientific fields. Scientific journals contain articles that have been peer-reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity.

The standards that a journal uses to determine publication can vary widely. Some journals, such as Nature and Science, will not publish an article unless they believe that it marks a fundamental breakthrough in its field, and hence will reject papers which contain good work that does not meet these criterion. Other journals, such as Astrophysical Journal or Physical Review will generally accept articles unless the referees believe that the paper is hopelessly and fundamentally flawed. It is also common for journals to have a regional focus, specializing in publishing papers from a particular geographic region.

Articles tend to be highly technical, representing the latest theoretical research and experimental results in the field of science covered by the journal. They are often incomprehensible to anyone except for researchers in the field. Scientific journals are a crucial part of the scientific literature.

Current issues in scientific journal publishingEdit

It has been argued that peer-reviewed paper journals are in the process of being replaced by electronic publishing. There is usually a delay of several months after an article is written before it is published in a journal and this makes journals not an ideal format for disseminating the latest research. In some fields such as astronomy, the role of the journal at disseminating the latest research has largely been replaced by preprint databases such as However, scientific journals still provide an important role in quality control, archiving papers, and establishing scientific credit. In general, the electronic material uploaded to preprint database are still intended for eventual publication in a peer-reviewed journal.

Another controversy is the cost of scientific journals and the fact that copyright is assigned to the journal publisher. Many scientists and librarians have protested against the cost of journals, especially as they see these fees going to large for-profit publishing houses.

There is an article titled "Online or Invisible?" (see link at end of article) uses statistical arguments to claim that electronic publishing provides wider dissemination. A number of journals have, while retaining their peer review process, established electronic versions or even moved entirely to electronic publication.

Types of journal articles Edit

There are four types of journal articles:

  1. Letters (which should not be confused with letters to the editor) are short usually one or two page descriptions of current research findings.
  2. Articles are usually between five and twenty pages and are a complete descriptions of current original research finding, but there are considerable variations between scientific fields and journals: 80-page articles are not rare in mathematics or theoretical computer science.
  3. Supplemental articles contain a large volume of tabular data that is the result of current research and may be dozens or hundreds of pages with mostly numerical data.
  4. Review articles do not cover original research but rather are long in-depth overviews of current research work on a particular topic.

The format of letters and articles are generally fixed. They begin with an abstract which is a two to four paragraph summary of the paper. An introduction which describes the background for the research including a discussion of similar research. A results and discussion section which describes the results and implications of the research, and a conclusion section which places the research in context and describes avenues for further exploration.

In addition to the above, some scientific journals such as Science will include a news section where scientific developments (often involving political issues) are described. These articles are often written by science journalists and not by scientists. In addition some journals will include an editorial section and a section for letters to the editor. Interestingly, while these are articles published within a journal, they are not generally regarded as scientific journal articles because they have not been peer reviewed.
