Scientific literature

Scientific literature comprises scientific publications that report original empirical and theoretical work in the natural and social sciences, and within a scientific field is often abbreviated as the literature. Academic publishing is the process of placing the results of one's research into the literature. Original scientific research published for the first time in scientific journals is called the primary literature. Patents and technical reports, for minor research results and engineering and design work (including computer software), can also be considered primary literature. Secondary sources include review articles (which summarize the findings of published studies to highlight advances and new lines of research) and books (for large projects or broad arguments, including compilations of articles).Tertiary sources might include encyclopedias and similar works intended for broad public consumption.
                                    Scientific literature can include the following kinds of publications:

• scientific articles published in scientific journals
• patents specialized for science and technology (for example, biological patents and chemical patents)
• books wholly written by one or a small number of co-authors
• edited volumes, where each chapter is the responsibility of a different author or set of authors, while the editor is responsible for determining the scope of the project, keeping the work on schedule, and ensuring consistency of style and content
• presentations at academic conferences, especially those organized by learned societies
• government reports such as a forensic investigation conducted by a government agency such as the NTSB
• scientific publications on the World Wide Web
• books, technical reports, pamphlets, and working papers issued by individual researchers or research organizations on their own initiative; these are sometimes organised into a series
• blogs and science forums

The significance of these different components of the literature varies between disciplines and has changed over time. As of 2006, peer-reviewed journal articles remain the predominant publication type, and have the highest prestige. However, journals vary enormously in their prestige and importance, and their status can influence the visibility and impact of the studies they publish. The significance of books, also called research monographs, depends on the subject. Generally books published by university presses are usually considered more prestigious than those published by commercial presses.^{[citation needed]} The status of working papers and conference proceedings depends on the discipline; they are typically more important in the applied sciences. The value of publication as a preprintor scientific report on the web has in the past been low, but in some subjects, such as mathematics or high energy physics, it is now an accepted alternative.

                                                  The actual day-to-day records of scientific information are kept in research notebooks or logbooks. These are usually kept indefinitely as the basic evidence of the work, and are often kept in duplicate, signed, notarized, and archived. The purpose is to preserve the evidence for scientific priority, and in particular for priority for obtaining patents. They have also been used in scientific disputes. Since the availability of computers, the notebooks in some data-intensive fields have been kept as database records, and appropriate software is commercially available.

The work on a project is typically published as one or more technical reports, or articles. In some fields both are used, with preliminary reports, working papers, or preprints followed by a formal article. Articles are usually prepared at the end of a project, or at the end of components of a particularly large one. In preparing such an article vigorous rules for scientific writing have to be followed.

                                                        A scientific article has a standardized structure, which varies only slightly in different subjects. Ultimately, it is not the format that is important, but what lies behind it - the content. However, several key formatting requirements need to be met:

1. The title attracts readers' attention and informs them about the contents of the article. Titles are distinguished into three main types: declarative titles (state the main conclusion), descriptive titles (describe a paper's content), and interrogative titles (challenge readers with a question that is answered in the text). Some journals indicate, in their instructions to authors, the type (and length) of permitted titles.
2. The names and affiliations of all authors are given. In the wake of some scientific misconduct cases, publishers often require that all co-authors know and agree on the content of the article.
3. An abstract summarizes the work (in a single paragraph or in several short paragraphs) and is intended to represent the article in bibliographic databases and to furnish subject metadata for indexing services.
4. The content should be presented in the context of previous scientific investigations, by citation of relevant documents in the existing literature, usually in a section called an "Introduction".
5. Empirical techniques, laid out in a section usually called "Materials and Methods", should be described in such a way that a subsequent scientist, with appropriate knowledge of and experience in the relevant field, should be able to repeat the observations and know whether he or she has obtained the same result. This naturally varies between subjects, and does not apply to mathematics and related subjects.
6. Similarly, the results of the investigation, in a section usually called "Results", data should be presented in tabular or graphic form (image, chart, schematic, diagram or drawing). These display elements should be accompanied by a caption and discussed in the text of the article.
7. Interpretation of the meaning of the results is usually addressed in a "Discussion" or "Conclusion" section. The conclusions drawn should be based on the new empirical results while taking consideration prior knowledge, in such a way that any reader with knowledge of the field can follow the argument and confirm that the conclusions are sound. That is, acceptance of the conclusions must not depend on personal authority, rhetorical skill, or faith.
8. Finally, a "References" or "Literature Cited" section lists the sources cited by the authors in the format required by the journal.
