Reference books and information are great places to look when beginning your research. Reference materials provide reliable background information and facts upon which you can build your research.
For online reference sources, try these databases, which contain background information on scientific topics:
"MedlinePlus will direct you to information to help answer health questions. MedlinePlus brings together authoritative information from The National Library of Medicine (NLM), the National Institutes of Health (NIH), and other government agencies and health-related organizations."
Consumer Health Complete
"Consumer Health Complete (CHC) is a comprehensive resource for consumer-oriented health content, including full text from many health reference books and encyclopedias and thousands of health reports as well as physician-generated videos and hundreds of medical images and diagrams. This full-text database covers topics such as aging, cancer, diabetes, drugs and alcohol, fitness, nutrition and dietetics, children's health, men and women's health, and more."
"The Encyclopædia Britannica database includes thousands of articles from the printed Encyclopædia Britannica, including thousands more that are not found in the print set. The resource also includes year-in-review articles from recent yearbooks, The Britannica Student Encyclopedia, and Merriam-Webster's Collegiate Dictionary and Thesaurus. Most articles are brief or of moderate length and discuss people, places, institutions, things, or concepts. Longer articles are divided into separate sections for easier access and more accurate searching."
