Blogger FemaleScienceProfessor has a great article up at the Chronicle of Higher Education about academic etiquette. Amusing and informative — and good for people who work in many walks of life, as well. (Particularly, some good advice about job searching from the points of view of both applicant and hiring committee.) And I have to love tip # 11:

If you are going to ask a professor a question and you need to refer to your notes or a book, have them within easy reach, with the relevant pages marked. Don’t spend the first few minutes searching through your backpack and your giant folders covered with skull doodles only to realize that you left the desired item at home and have no idea what your question was, so instead you just ask the professor if you missed anything important in the class session you skipped because you overslept.
