Evidence from bibliometric and scientometric analyses confirms that the trend toward larger author lists on scientific papers is largely driven by expansive national and international research collaborations.
The claim posits that large author lists reflect contributions from massive research collaborations. Papers [2] and [6] specifically examine authorship trends and collaborative team sizes, demonstrating that growing author bylines are associated with larger team sizes, multi-author contributions, and international collaborations. Thus, the available evidence clearly supports the claim.
