Reply #9: Contact your department.

If there's another professor in your department that you have a good relationship with, you might start with them. If not, contact the department secretary. Make it clear that Friday is an important deadline for you and that you haven't received any response to multiple emails, not even a "working on it" message.

If your advisor is on sabbatical or doing summer research at another university, contact the "home" department first -- she will be more known by and accountable to the people she usually works with/for than a place she may only be visiting for the summer and it's the requirements of the home institution that need to be met.

If you get no response whatsover from your department, go to the dean for your school/college or the grad/undergrad dean (whichever you are).
