The list of authors attached to a paper has provided a comfortable device for apportioning attribution for centuries - not only is it simple and clear, we all have a good idea of what ‘authoring’ implies.

However, with the increasing migration of content to an online environment, the number of ways in which papers can be connected has exploded. We expect references and citations to click through, we want to see what else authors have written, and we are keen to discover who they have collaborated with.

But while this connectivity establishes that there is a link between an author and a paper, it says nothing about the nature of that link. Did the author write the experiment, analyze the data, or were they responsible for running the research program, ie. had very little to do with this particular article?

Bridging the discipline gulf

Depending on your field, you may be thinking about the order in which the authors are assembled, and how you can use this to make sense of their relative status. However, a researcher in another field may interpret that same list quite differently. This is illustrated in the table below in which we take a look at a fictional paper written by Smith, Taylor and Thorisson.

 High Energy Physics Author list is in alphabetic order, no precedence can be interpreted. Names may include engineers as well as researchers, in this case we could add Bercow, a PhD student who ran the experiment and took care of writing computer algorithms, ensuring the integrity of the data and selecting candidates for trials, etc...
 Economics, some fields
within Social Sciences
Author list is in alphabetic order, no precedence can be interpreted.
 Life Sciences Smith the postdoc did most of the experimental work, but Thorisson was the principal investigator who led the scientific direction of the work. The alphabetical order is coincidental.
 ‘Standard’ order Smith is the senior researcher who did most of the work. Taylor was subordinate to Smith, Thorisson is subordinate to Taylor. The alphabetical order is coincidental.

One of the advantages that a reconceptualization of authorship offers us is the proper acknowledgement of work undertaken during the research process without conferring a higher status than is merited. For example, work that is undertaken on computer algorithms would not (at the moment) usually confer authorship by itself – however, a move towards a contributorship model would enable the correct communication of the algorithm creator's contribution.

As publishing opens up, and platforms become more integrated, we are likely to become more exposed to articles that are outside our field, and others that are interdisciplinary. If we can’t rely on the author order to help us make sense of what authorship has meant for a particular paper, can we at least be sure about the class of activity that merits authorship attribution?

With the exception of high energy physics, which will include engineers along with researchers in the authorship list, it’s a surprisingly difficult activity to undertake. There is an extensive and growing literature available covering the ethical dilemmas that arise from attribution.

Understanding the rules

The most widely used authorship rules are known as the ’Vancouver rules’ and were laid down by the International Committee of Medical Journal Editors (ICMJE)[1]. The rules, which are followed by several hundred journals – mostly medical - specify that:

“Authorship credit should be based on: 1) substantial contributions to conception and design, acquisition of data, or analysis and interpretation of data; 2) drafting the article or revising it critically for important intellectual content; and 3) final approval of the version to be published. Authors should meet conditions 1, 2, and 3.

Although these rules are clear and many journals are signed up to follow them, there is evidence that compliance is far from complete, and that the rules are not well understood. In fact, exploring alternative models was the focus of the International Workshop on Contributorship and Scholarly Attribution [2], hosted by IQSS (The Institute for Quantitative Science) at Harvard in May last year. Those of us with experience in publishing would recognize the issues involved in getting hundreds of authors to give final approval to a document: and some fields have published manuscripts where authorship is well into the thousands.

Two phenomena that have become recognized over the last few years are ‘ghost’ authorship and ‘guest’ authorship. Guest authorship occurs when an author’s name is included on the authoring list despite them not having played any part in the research or authoring process. This can come about in a variety of ways: when it is ‘normal lab practice’ to include the head of the lab on all publications; when a researcher has left the organization before the paper is written; and in the hope that a senior and well-respected name will confer additional credibility on a research paper and improve the chances of publication in a high-impact journal. Ghost authorship is a phenomenon that is said to occur when interested parties employ a professional writer, or have staff members on the research team, but don’t include these individuals on the final publications list. The implication is that these people would have a conflict of interest in the outcome of the research (or at least the presentation of the research at publication). By omitting their names, the paper affiliations look more neutral. There is a variety of other literature [3] in this area, alleging political / organizational influence in the creation of authorship lists. There is also some evidence that – when computed – tasks that would have previously conferred authorship no longer have this advantage.

As publishing articles is frequently considered to be the main currency of academic recognition – and is increasingly included in formal rule sets that govern academic status and eligibility for funding – so we can expect an increase in the heat governing this debate. Potentially, if the number of authors included in an article continues to increase, we may also witness a decrease in the value of authorship.

Adopting a contributorship approach

So what about contributorship, and how does it relate to authorship? Authorship is bound to persist into the future, for both ethical and copyright / legal reasons, so contributorship needs to be seen as an extension of existing protocols.

In short, the idea behind contributorship is to disclose what activities the researcher undertook to merit a place on the author list. Research undertaken by the author and colleagues in 2012 indicates that nearly all activities can be classified into a set of between 12 and 15 categories. The first three of these are outlined in Table 2 below. Although the prospect of this additional task as a manual activity would – quite properly – concern all people involved in the authoring and publishing process, this work could be a feature of the various research and collaboration tools (e.g. Mendeley) and services such as ORCID (footnote: ORCID was designed to enable definitions richer than authorship).

Conceptual and intellectual Formulation of the research questions; design of the experiments; interpretation of the results; intellectual and moral responsibility for the integrity of the paper, as a whole and for individual contributions.
Technical and experimental Implementation of the investigation and undertaking of experiments; obtaining specimens and subjects; acquisition and processing of data; analysis of results.
Organizational and communication Writing the project proposal and obtaining funding; ensuring compliance, e.g. ethics committees’ approval, informed consent; writing up results into a paper; illustration of the paper – selection and use of data; reporting.

Table 2. Three of the categories proposed to classify contributorship

Relationships are changing; we are moving towards a richer world with a more detailed and nuanced web of connections.  Although the concept of authorship is rooted in our culture and in our minds, contributorship could offer a richer set of definitions, enabling our contributions to human knowledge to be recorded more precisely. The value to us will be in knowing the areas of our expertise and contribution. If the cost is ameliorated through intelligent tools and services, then we can expect to see contributorship becoming one of the hot topics in scholarly communications and publishing.
