Academic authorship of journal articles, books, and other original works is a means by which academics communicate the results of their scholarly work, establish priority for their discoveries, and build their reputation among their peers.
Authorship is a primary basis that employers use to evaluate academic personnel for employment, promotion, and tenure. In academic publishing, authorship of a work is claimed by those making intellectual contributions to the completion of the research described in the work. In simple cases, a solitary scholar carries out a research project and writes the subsequent article or book. In many disciplines, however, collaboration is the norm and issues of authorship can be controversial. In these contexts, authorship can encompass activities other than writing the article; a researcher who comes up with an experimental design and analyzes the data may be considered an author, even if he had little role in composing the text describing the results. According to some standards, even writing the entire article would not constitute authorship unless the writer was also involved in at least one other phase of the project.

Guidelines for assigning authorship vary between institutions and disciplines. They may be formally defined or simply cultural custom. Incorrect application of authorship rules occasionally leads to charges of academic misconduct and sanctions for the violator. A 2002 survey of a large sample of researchers who had received funding from the U.S. National Institutes of Health revealed that 10% of respondents claimed to have inappropriately assigned authorship credit within the last three years. This was the first large scale survey concerning such issues. In other fields only limited or no empirical data is available.
Authorship in the natural sciences
The natural sciences have no universal standard for authorship, but some major multi-disciplinary journals and institutions have established guidelines for work that they publish. The journal Proceedings of the National Academy of Sciences of the United States of America (PNAS) has an editorial policy that specifies "authorship should be limited to those who have contributed substantially to the work" and furthermore, "authors are strongly encouraged to indicate their specific contributions" as a footnote. The American Chemical Society further specifies that authors are those who also "share responsibility and accountability for the results" and the U.S. National Academies specify "an author who is willing to take credit for a paper must also bear responsibility for its contents. Thus, unless a footnote or the text of the paper explicitly assigns responsibility for different parts of the paper to different authors, the authors whose names appear on a paper must share responsibility for all of it."
Authorship in mathematics, theoretical computer science and high energy physics
In mathematics, the authors are usually listed in alphabetical order (this is the so-called Hardy-Littlewood Rule). This usage is described in the "Information Statements on the Culture of Research and Scholarship in Mathematics" section of the American Mathematical Society website, specifically the 2004 statement: Joint Research and Its Publication.
In other branches of knowledge such as economics, business, finance or particle physics, it is also usual to sort the authors alphabetically.
Authorship in medicine
The medical field defines authorship very narrowly. According to the Uniform Requirements for Manuscripts Submitted to Biomedical Journals, designation as an author must satisfy three conditions. The author must have:
- Contributed substantially to the conception and design of the study, the acquisition of data, or the analysis and interpretation
- Drafted or provided critical revision of the article
- Provided final approval of the version to publish
Acquisition of funding, or general supervision of the research group alone does not constitute authorship. Many medical journals have abandoned the strict notion of author, with the flexible notion of contributor.
Between about 1980-2010 the average number of authors in medical papers increased, and perhaps tripled.
The  While the APA guidelines list many other forms of contributions to a study that do not constitute authorship, it does state that combinations of these and other tasks may justify authorship. Like medicine, the APA considers institutional position, such as Department Chair, insufficient for attributing authorship.
Authorship in the humanities
Neither the Modern Languages Association nor the Chicago Manual of Style define requirements for authorship (because usually humanities works are single-authored and the author is responsible for the entire work).
From the late 17th century to the 1920s, sole authorship was the norm, and the one-paper-one-author model worked well for distributing credit. Today, shared authorship is common in most academic disciplines, with the exception of the humanities, where sole authorship is still the predominant model. In particular types of research, including particle physics, genome sequencing and clinical trials, a paper's author list can run into the hundreds. In large, multi-center clinical trials authorship is often used as a reward for recruiting patients. A paper published in the New England Journal of Medicine in 1993 reported on a clinical trial conducted in 1,081 hospitals in 15 different countries, involving a total of 41,021 patients. There were 972 authors listed in an appendix and authorship was assigned to a group. In the summer of 2008, an article in high-energy physics was published describing the Large Hadron Collider, a 27 mile long particle accelerator that crosses the Swiss–French border; the article boasted 2,926 authors from 169 research institutions.
Long author lists strain guidelines that insist that each author's role be described and that each author is responsible for the validity of the whole work. One Big Science facility, the Collider Detector at Fermilab (CDF), in 1998 adopted a highly unorthodox policy for assigning authorship. CDF maintains a standard author list. All scientists and engineers working at CDF are added to the standard author list after one year of full-time work; names stay on the list until one year after the worker leaves CDF. Every publication coming out of CDF uses the entire standard author list, in alphabetical order. Such a system treats authorship more as credit for scientific service at the facility in general rather that as an identification of specific contributions.
Large authors lists have attracted some criticism. One commentator wrote, "In more than 25 years working as a scientific editor ... I have not been aware of any valid argument for more than three authors per paper, although I recognize that this may not be true for every field." The rise of shared authorship has been attributed to Big Science—scientific experiments that require collaboration and specialization of many individuals.
Alternatively, the increase in multi-authorship might be a consequence of the way scientists are evaluated. Traditionally, scientists were judged by the number of papers they published, and later by the impact of those papers. The former is an estimate of quantity and the latter of quality. Both methods were adequate when single authorship was the norm, but vastly inflate individual contribution when papers are multi-authored. When each author claims each paper and each citation as his/her own, papers and citations are magically multiplied by the number of authors. Furthermore, there is no cost to giving authorship to individuals who made only minor contribution and there is an incentive to do so. Hence, the system rewards heavily multi-authored papers. This problem is openly acknowledged, and it could easily be "corrected" by dividing each paper and its citations by the number of authors.
Finally, the rise in shared authorship may also reflect increased acknowledgment of the contributions of lower level workers, including graduate students and technicians, as well as honorary authorship.
Honorary authorship is sometimes granted to those who played no significant role in the work, for a variety of reasons. Until recently, it was standard to list the head of a German department or institution as an author on a paper regardless of input. The United States National Academy of Sciences, however, warns that such practices "dilute the credit due the people who actually did the work, inflate the credentials of those so 'honored,' and make the proper attribution of credit more difficult." The extent to which honorary authorship still occurs is not empirically known. However, it is plausible to expect that it is still widespread, because senior scientists leading large research groups can receive much of their reputation from a long publication list and thus have little motivation to give up honorary authorships.
A possible measure against honorary authorships has been implemented by some scientific journals, in particular by the Nature journals. They demand that each new manuscript must include a statement of responsibility that specifies the contribution of every author. The level of detail varies between the disciplines. Senior persons may still make some vague claim to have "supervised the project", for example, even if they were only in the formal position of a supervisor without having delivered concrete contributions. (The truth content of such statements is usually not checked by independent persons.) However, the need to describe contributions can at least be expected to somewhat reduce honorary authorships. In addition, it may help to identify the perpetrator in a case of scientific fraud.
Ghost authorship occurs when an individual makes a substantial contribution to the research or the writing of the report, but is not listed as an author. Researchers, statisticians and writers (e.g. medical writers or technical writers) become ghost authors when they meet authorship criteria but are not named as an author. Writers who work in this capacity are called ghostwriters.
Ghost authorship has been linked to partnerships between industry and higher education. Two-thirds of industry-initiated randomized trials may have evidence of ghost authorship. Ghost authorship is considered problematic because it may be used to obscure the participation of researchers with conflicts of interest.
Litigation against the pharmaceutical company, Merck over health concerns related to use of their drug, Rofecoxib (brand name Vioxx), revealed examples of ghost authorship. Merck routinely paid medical writing companies to prepare journal manuscripts, and subsequently recruited external, academically affiliated researchers to pose as the authors.
Authors are sometimes included in a list without their permission. Even if this is done with the benign intention to acknowledge some contributions, it is problematic since authors carry responsibility for correctness and thus need to have the opportunity to check the manuscript and possibly demand changes.
Rules for the order of multiple authors in a list vary significantly between fields of research, but are generally consistent within a particular field. Some fields list authors in order of their degree of involvement in the work, with the most active contributors listed first; other fields, such as mathematics or engineering (e.g.,

Scientists and engineers working in corporate and military organizations are often restricted from publishing and claiming authorship of their work because their results are considered secret property of the organization that employs them. One notable example is that of William Gosset, who was forced to publish his work in statistics under the pseudonym “Student” due to his employment at the Guinness brewery. Another account describes the frustration of physicists working in nuclear weapons programs at the Lawrence Livermore Laboratory – years after making a discovery they would read of the same phenomenon being "discovered" by a physicist unaware of the original, secret discovery of the phenomenon.
In the 18th century, Émilie du Châtelet began her career as a scientific author by submitting a paper in an annual competition held by the French Academy of Sciences; papers in this competition were submitted anonymously. Initially presenting her work without claiming authorship allowed her to have her work judged by established scientists while avoiding the bias against women in the sciences. She did not win the competition, but eventually her paper was published alongside the winning submissions, under her real name.
Authors occasionally forgo claiming authorship, for a number of reasons. Historically some authors have published anonymously to shield themselves when presenting controversial claims. A key example is Robert Chambers' anonymous publication of Vestiges of the Natural History of Creation, a speculative, pre-Darwinian work on the origins of life and the cosmos. The book argued for an evolutionary view of life in the same spirit as the late Frenchman Jean-Baptiste Lamarck. Lamarck had long been discredited among intellectuals by this time and evolutionary (or development) theories were exceedingly unpopular, except among the political radicals, materialists, and atheists - Chambers hoped to avoid Lamarck's fate.
Additionally, authors are expected to keep all study data for later examination even after publication. Both scientific and academic censure can result from a failure to keep primary data; the case of Ranjit Chandra of Memorial University of Newfoundland provides an example of this. Many scientific journals also require that authors provide information to allow readers to determine whether the authors may have commercial or non-commercial conflicts of interest. Outlined in the author disclosure statement for the American Journal of Human Biology, this is a policy more common in scientific fields where funding often comes from corporate sources. Authors are also commonly required to provide information about ethical aspects of research, particularly where research involves human or animal participants or use of biological material. Provision of incorrect information to journals may be regarded as misconduct. Financial pressures on universities have encouraged this type of misconduct. The majority of recent cases of alleged misconduct involving undisclosed conflicts of interest or failure of the authors to have seen scientific data involve collaborative research between scientists and biotechnology companies.
All authors, including co-authors, are usually expected to have made reasonable attempts to check findings submitted for publication. In some cases, co-authors of faked research have been accused of inappropriate behavior or research misconduct for failing to verify reports authored by others or by a commercial sponsor. Examples include the case of Professor Geoffrey Chamberlain named as guest author of papers fabricated by Malcolm Pearce, (Chamberlain was exonerated from collusion in Pearce's deception) and the co-authors of Jan Hendrik Schön at Bell Laboratories. More recent cases include Charles Nemeroff, former editor-in-chief of Neuropsychopharmacology, and the so-called Sheffield Actonel affair.
In a notable case, American stem-cell researcher Gerald Schatten had his name listed on a paper co-authored with Hwang Woo-suk. The paper was later exposed as fraudulent and, though Schatten was not accused of participating in the fraud, a panel at his university found that "his failure to more closely oversee research with his name on it does make him guilty of 'research misbehavior.'"
Authors' reputations can be damaged if their names appear on a paper that they do not completely understand or with which they were not intimately involved. Numerous guidelines and customs specify that all co-authors must be able to understand and support a paper's major points.
Although listing authors in order of the involvement in the project seems straightforward, it often leads to conflict. A study in the Canadian Medical Association Journal found that more than two-thirds of 919 corresponding authors disagreed with their coauthors regarding contributions of each author.
Research articles in high energy physics, where the author lists can number in the tens to hundreds, often list authors alphabetically. However, the practice of putting the principal investigator last in the author list has become the common standard across most areas in science and engineering. In Computer Science in general the principal contributor is the first in the author list.
