Histology hint from Sarah Bellham: If you are studying histology or involved in health care, you need a medical dictionary. You may as well get one as early in your career as possible to maximize the benefit. I recommend: Stedman's Medical Dictionary or Dorland's Illustrated Medical Dictionary, 30th Edition.
