I've talked a surprising number of graduate students in several disciplines, all in the same bind:
- They have a very senior and well respected academic as a coauthor
- That coauthor has been sitting on the manuscript for a year or more
- They have written several followups with no luck.
- They can't (or feel they can't) pull that person from the paper,
partly for desire to benefit from the glow of fame, but largely for fear of offending this kind of person, who so often functions as a gatekeeper to their discipline.
I don't know what to tell them, besides keep following up, or give up on getting the paper published. Any better advice?
