Scientific journal
Encyclopedia
In academic publishing
, a scientific journal is a periodical publication
intended to further the progress of science
, usually by reporting new research
. There are thousands of scientific journals in publication, and many more have been published at various points in the past (see list of scientific journals). 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 review
ed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity
. Although scientific journals are superficially similar to professional
magazine
s, they are actually quite different. Issues of a scientific journal are rarely read casually, as one would read a magazine. The publication of the results of research is an essential part of the scientific method
. If they are describing experiments or calculations, they must supply enough details that an independent researcher could repeat the experiment or calculation to verify the results. Each such journal article becomes part of the permanent scientific record.
The history of scientific journals dates from 1665, when the French Journal des sçavans
and the English Philosophical Transactions of the Royal Society
first began systematically publishing research results. Over a thousand, mostly ephemeral
, were founded in the 18th century, and the number has increased rapidly after that.
Articles in scientific journals can be used in research and higher education. Some classes are partially devoted to the explication of classic articles, and seminar
classes can consist of the presentation by each student of a classic or current paper. In a scientific research group or academic department
it is usual for the content of current scientific journals to be discussed in journal club
s.
The standards that a journal uses to determine publication can vary widely. Some journals, such as Nature
, Science
, PNAS, and Physical Review Letters
, have a reputation of publishing articles that mark a fundamental breakthrough in their respective fields. In many fields, an informal hierarchy of scientific journals exists; the most prestigious journal in a field tends to be the most selective in terms of the articles it will select for publication, and will also have the highest impact factor
. It is also common for journals to have a regional focus, specializing in publishing papers from a particular country or other geographic region, like African Invertebrates
.
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 and advanced students. In some subjects this is inevitable given the nature of the content. Usually, rigorous rules of scientific writing
are enforced by the editors; however, these rules may vary from journal to journal, especially between journals from different publishers.
The formats of journal articles vary, but many follow the general IMRAD
scheme recommended by the International Committee of Medical Journal Editors (ICMJE). Such articles begin with an abstract
, which is a one-to-four-paragraph summary of the paper. The introduction describes the background for the research including a discussion of similar research. The materials and methods or experimental section provides specific details of how the research was conducted. The results and discussion section describes the outcome and implications of the research, and the conclusion section 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. While these are articles published within a journal, in general they are not regarded as scientific journal articles because they have not been peer-reviewed.
Electronical publishing will exist alongside paper publishing, because printed paper publishing is not expected to disappear in the future. Output to a screen is important for browsing and searching but is not well adapted for extensive reading. Paper copies of selected information will definitely be required. Therefore the article has to be transmitted electronically to the reader's local printer. Formats suitable both for reading on paper, and for manipulation by the reader's computer will need to be integrated.
Electronic counterparts of established print journals already promote and deliver rapid dissemination of peer reviewed and edited, "published" articles. Other journals, whether spin-offs of established print journals, or created as electronic only, have come into existence promoting the rapid dissemination capability, and availability, on the Internet. In tandem with this is the speeding up of peer review, copyediting, page makeup, and other steps in the process to support rapid dissemination.
Other improvements, benefits and unique values of electronically publishing the scientific journal are lower cost, and availability to more people, especially scientists from non-developed countries. Hence, research results from more developed nations are becoming more accessible to scientists from non-developed countries.
Moreover, electronic publishing of scientific journals has been accomplished without compromising the standards of the refereed, peer review process.
One form is the online equivalent of the conventional paper journal. By 2006, almost all scientific journals have, while retaining their peer-review process, established electronic versions; a number have moved entirely to electronic publication. In similar manner, most academic libraries buy the electronic version, and purchase a paper copy only for the most important or most-used titles.
There is usually a delay of several months after an article is written before it is published in a journal, making paper journals not an ideal format for announcing the latest research. Many journals now publish the final papers in their electronic version as soon as they are ready, without waiting for the assembly of a complete issue, as is necessary with paper. In many fields in which even greater speed is wanted, such as physics
, the role of the journal at disseminating the latest research has largely been replaced by preprint
databases such as arXiv.org. Almost all such articles are eventually published in traditional journals, which still provide an important role in quality control
, archiving papers, and establishing scientific credit.
Publications by scholarly societies, also known as not-for-profit-publishers (NFP), usually cost less than commercial publishers, but the prices of their scientific journals are still usually several thousand dollars a year. In general, this money is used to fund the activities of the scientific societies that run such journals, or is invested in providing further scholarly resources for scientists; thus, the money remains in and benefits the scientific sphere.
Despite the transition to electronic publishing, the serials crisis
persists.
Concerns about cost and open access have led to the creation of free-access journals such as the Public Library of Science
(PLoS) family and partly open or reduced-cost journals such as the Journal of High Energy Physics
. However, professional editors still have to be paid, and PLoS still relies heavily on donations from foundations to cover the majority of its operating costs; smaller journals do not often have access to such resources.
An article titled "Online or Invisible?" has used statistical arguments to show that electronic publishing
online, and to some extent open access, both provide wider dissemination and increase the average number of citations an article receives. Lawrence postulates that papers that are easier to access are used more often and therefore cited more often.
to the journal publisher. Publishers claimed this was necessary in order to protect author's rights, and to coordinate permissions for reprints or other use. However, many authors, especially those active in the open access movement, found this unsatisfactory, and have used their influence to effect a gradual move towards a license to publish instead. Under such a system, the publisher has permission to edit, print, and distribute the article commercially, but the author(s) retain the other rights themselves.
Even if they retain the copyright to an article, most journals allow certain rights to their authors. These rights usually include the ability to reuse parts of the paper in the author's future work, and allow him to distribute a limited number of copies. In the print format, such copies are called reprints; in the electronic format, they are called postprints
. Some publishers, for example the American Physical Society
, also grant the author the right to post and update the article on the author's or employer's website and on free e-print servers, to grant permission to others to use or reuse figures, and even to reprint the article as long as no fee is charged. The rise of open access journals, in which the author retains the copyright but must pay a publication charge, such as the Public Library of Science
family of journals, is another recent response to copyright concerns.

Types of articles
There are several types of journal articles; the exact terminology and definitions vary by field and specific journal, but often include:- Letters (also called communications, and not to be confused with letters to the editor) are short descriptions of important current research findings that are usually fast-tracked for immediate publication because they are considered urgent.
- Research notes are short descriptions of current research findings that are considered less urgent or important than Letters.
- Articles are usually between five and twenty pages and are complete descriptions of current original research findings, but there are considerable variations between scientific fields and journals – 80-page articles are not rare in mathematicsMathematicsMathematics is the study of quantity, space, structure, and change.

Some journals now only publish this data electronically on the internet. - Review articles do not cover original research but rather accumulate the results of many different articles on a particular topic into a coherent narrative about the state of the art in that field. Review articles provide information about the topic and also provide journal references to the original research. Reviews may be entirely narrative, or may provide quantitative summary estimates resulting from the application of meta-analytical methodsMeta-analysisIn statistics, a meta-analysis combines the results of several studies that address a set of related research hypotheses.

Electronic publishing
Electronic publishing is a new area of information dissemination. One definition of electronic publishing is in the context of the scientific journal. It is the presentation of scholarly scientific results in only an electronic (non-paper) form. This is from its first write-up, or creation, to its publication or dissemination. The electronic scientific journal is specifically designed to be presented on the internet. It is defined as not being previously printed material adapted, or re-tooled, and then delivered electronically.Electronical publishing will exist alongside paper publishing, because printed paper publishing is not expected to disappear in the future. Output to a screen is important for browsing and searching but is not well adapted for extensive reading. Paper copies of selected information will definitely be required. Therefore the article has to be transmitted electronically to the reader's local printer. Formats suitable both for reading on paper, and for manipulation by the reader's computer will need to be integrated.

Cost
Many scientists and librarians have long protested the cost of journals, especially as they see these payments going to large for-profit publishing houses. To allow their researchers online access to journals, many universities purchase site licenses, permitting access from anywhere in the university, and, with appropriate authorization, by university-affiliated users at home or elsewhere. These may be quite expensive, sometimes much more than the cost for a print subscription, although this reflects the number of people who will be using the license; a print subscription is the cost for one person to receive the journal, whereas a site-license can let thousands of people access it.Publications by scholarly societies, also known as not-for-profit-publishers (NFP), usually cost less than commercial publishers, but the prices of their scientific journals are still usually several thousand dollars a year. In general, this money is used to fund the activities of the scientific societies that run such journals, or is invested in providing further scholarly resources for scientists; thus, the money remains in and benefits the scientific sphere.
