Links to various documents on this topic, from
a CS professor at the University of Maryland/Baltimore
County. She has lots of other good stuff (e.g.,
how to organize a workshop, how to present research,
etc., on her
website, under the heading
"Other Stuff"
"Looks at the many advantages of having your Ph.D.
students include a memo to you when seeking feedback on their
dissertation drafts."
Although aimed at faculty, I think the advice here
should be followed by anyone who is doing collaborative
writing with someone else. Grads: Take the advice here
even if your major professor doesn't require it!
