The Association for the Advancement of Science (AAAS), publishers of Science magazine, have put together a booklet of advice for people planning on a career in science. There are chapters on graduate school, skills for scientists, resumes and networking, non-traditional careers, diversity issues and others.
The articles were originally written for their careers web site and have been collected into an 88-page booklet. You can see the original articles, individual chapters, or download the whole booklet as a PDF file. And it's FREE.
