Publications are usually key to a career in science. This is why there are often conflicts about whether a person is included as author and if so at which position. Conventions vary by country and institution and change over time. But which criteria should be applied? The Vancouver Convention attempted to give an answer. Recently the Council of Science Editors has put forward a reworked guideline suggestion.
Guidelines on authorship have existed for decades. Studies have shown that they are not followed consistently and that many researchers remain unaware of them . Criteria on authorship seem to be based more on local customs than on consensus rules.
A new standard for authorship was put forward by Paul J. Friedman from the UCSC and the Council of Science Editors (CSE) . It might supersede the Vancouver scheme detailed below. One of its central points is to include a detailed list of author contributions.
Friedman suggest 2 or 3 of the below criteria as minimum requirement for authorship but adds that the appropriate minimum depends on "individual circumstances, such as the number of authors". This guideline would raise some contributors from acknowledgements to authors compared to the Vancouver agreement. It also recommends that persons who contributed in only 1 category be moved to acknowledgements.
|CONCEPT||the idea for the research or article, framing the hypothesis|
|DESIGN||planning the methods to generate results|
|SUPERVISION||oversight and responsibility for the organization and course of the project and the manuscript|
|RESOURCES||dollars, equipment, space, personnel vital to the project|
|MATERIAL||biological materials, reagents, referred patients|
|DATA COLLECTION/PROCESSING||responsibility for doing experiments, managing patients, organizing and reporting data|
|ANALYSIS/INTERPRETATION||responsibility for making sense of and presenting the results|
|LITERATURE SEARCH||responsibility for this necessary function|
|WRITING||responsibility for creating all or a substantive part of the manuscript|
|CRITICAL REVIEW||reworking the manuscript for intellectual content before submission, not just spelling and grammar checking|
|OTHER||for novel contributions|
Uniform Requirements (Vancouver Convention)
Authors: The International Committee of Medical Journal Editors (ICMJE) = the Vancouver group
Summary: authorship requires "substantial contribution" to EITHER
- conception and design
- acquisition of data
- analysis and interpretation of data
The editors committee also emphasises that drafting or revising and the final approval of the version to be published are necessary for authorship.
Criteria not sufficient for authorship are:
- acquisition of funding
- general supervision of the research group
(This section is ambiguously worded in the original text. It also includes "collection of data" as a criterium not sufficient for authorship while listing "acquisition of data" as a contribution sufficient for authorship.)

R. D. Ganatra criticises the following points: "These guidelines were established to safeguard the position of the editors of journals and are concerned primarily with the written version of a scientific paper. They do not consider how the research project was conducted and who collected experimental data. They ignore technicians who slog to collect the data reported. The guidelines say nothing about researchers who have contributed to the work but whose names are left out of the paper." 
Is the Vancouver Convention too vague? Consider this quote of an arbiter explaining the convention: "To be a co-author, a person’s contribution must be substantial, it must be related to the project and the author must have participated in the whole process with critical reflection." Knut Ruyter, National Committee for Medical Research Ethics (NEM). What is substantial is a common question asked.
