You are contributing to one of the most widely read resources on the web. Congrats! This will be a memorable experience.  I'm glad to help you find the right resources as part of the process.

Go HERE to learn what Wikipedia prefers as reliable sources.  Pay particular attention to the section on "Scholarship."

More from Wikipedia about what to look for in sources: 

• Independent sources, that is, those not directly related to the subject or written by the subject.
• Sources known for fact-checking and neutrality, such as academic presses, peer-reviewed journals, or international newspapers.
• Reliable publishers that represent a general consensus in the field (ask your instructor or librarian about a publication if you're not sure it's reliable).

For this class, you will need to use Medical Reliable Sources (MEDRS) (source: Wikipedia)

Good sources (from Wikipedia training module):

• are typically no more than 5 years old
• summarize secondary sources or many primary sources
• provide an overview of the current understanding of the topic
• combine the results of several studies
• are published independently of the research

Some good examples of MEDRS:

• literature reviews or systematic reviews found in reputable medical journals
• academic and professional books written by experts in the relevant field, from a respected publisher
• medical guidelines or position statements from nationally or internationally recognized expert bodies
