I have a few ‘rules’ (a.k.a. ‘guidelines’) in my lab about the authorship of articles, but I’ve come to realise that each article requires its own finessing each time authorship is in question. After a lengthy discussion yesterday with the members of Franck Courchamp‘s lab, I decided I should probably write down my thoughts on this, one of the stickiest of subjects in the business of science.
The following discussion can be divided into to two main categories: (1) who to include as a co-author, and once the list of co-authors has been determined, (2) in what order should they be listed?
Before launching into discussing the issues related to Category 1, it is prudent to declare that there are as probably as many conventions as there are publishing scientists, and each discipline’s most general conventions differ across the scientific spectrum. I’m sure if you asked 10 people about what they considered appropriate, you could conceivably receive 10 different answers.
That said, I do still think there are some good-behaviour guidelines on authorship that one should strive to follow, all of which are based on my own experiences (both good and awful).
So who to include? It seems like a simple question superficially because clearly if someone contributed to writing a peer-reviewed article, he/she should be listed as a co-author. The problem really doesn’t concern the main author (the person who did most of the actual composition) because it’s clear here who that will be in almost every case. In most circumstances, this also happens to be the lead author (but more on that below). The question should really apply then to those individuals whose effort was more modest in the production of the final paper.
Strictly speaking, an ‘author’ should write words; but how many words do they need to write before being included? Would 10 suffice, or at least 10%? You can see why this is in itself a sticky subject because there are no established or accepted thresholds. Of course, science generally requires much more than just writing words: there are for most papers experiments to design, grants to obtain to fund them, data to collect, analysis and modelling to be done, figures and tables to prepare and finally, words to write. I’ll admit that I’ve co-authored many papers where I’ve done mainly one of those things (analysis, data collection, etc.), but I can also hold my hand over my heart and state that I’ve contributed more than a good deal to the actual writing of the paper in all circumstances where I’ve been listed as a co-author (the amount of which depends entirely on the lead author’s writing capacity).
