Who needs and uses health sciences library information services? A surgeon needs a review of the latest opinions on bariatric surgery. A pharmacist needs the U.S. equivalent name for a drug prescribed in Europe. A nurse wants advice on pediatric terminal care. A physical therapist wants information on rehabilitation after a broken collarbone. A student is working on the biochemical explanation for the benefits (or not) of certain herbal teas. A rural physician urgently needs to update her skills in performing an appendectomy. A retired faculty member is writing a book on the arguments about using mitochondrial DNA for tracing population genetics. Intriguing? Whetting the appetite of the reference sleuth?
