As a coauthor, I occasionally receive requests for full-text pdfs of research I have worked on in the past (vis Researchgate for instance). Thus far I have generally ignored those requests - leaving it up to the first or corresponding author to reply.
However, when these requests lay dormant for a while I would like to know what the etiquette would be for providing the full text as a middle author?
Advantages:
- Share my work more widely, also increases visibility for the first author/senior author.
- Coauthors may have drifted away from academia, or not be on the platform.
Disadvantages:
- Not sure of the interface on Researchgate - but if they have explicitly ignored the request and then I accept it I have acted against their interest.
