How much time should a coauthor be allowed for reviewing a manuscript before it is submitted? How long is too long? At what point do you feel it is appropriate to start complaining? Or making ultimatums?
What if that coauthor is your advisor?
What if that coauthor is your student?
Personally, I think things are going pretty well if all coauthors respond to a request for feedback within a month. Gentle reminders are appropriate beginning about three weeks after the coauthors receive the manuscript, and can increase in frequency and sternness of tone after that. I think three months is too long, unless there are extenuating circumstances, and is the point at which serious complaining may start. I can't imagine making an ultimatum to an advisor or coauthor who made a major contribution, but I can imagine engaging in hard-core whining.
Am I off base?
