MedlinePlus is a great place to start when you are seeking information on a wide range of subjects in the medical field. For example, under the Health Topics page, you can search; Body Location/Systems, Disorders & Conditions, Diagnosis and Theory, Health & Wellness, or Demographic Groups.
Do you want to know the effects of a certain drug? It's here. Do you have an upcoming surgery? Find out what preparation is needed and choose from a list of surgical video recordings. What about immunization schedules for children you ask?! You guessed it.
Browsers may also choose English or Spanish language text. (I really like the Merriam Webster search component for when I don't know how to spell what I'm trying to find.) This site has a great collection of interactive tutorials and videos. Wow!
MedlinePlus is just one of the many excellent databases offered by the San José Public Library.
