Original sources and other scholarly readings

Scholarly research requires reading original sources, including the speech that a president actually delivered, not a summary of the speech. Scholarly articles in peer-reviewed journals should be read in addition to the summaries provided in newspaper articles or on television news. Accessing all types of information is an important step in understanding an issue from many different perspectives.

Many scientific articles are available from the National Institutes of Health, National Library of Medicine (NLM). We have provided the NLM PubMed link for those articles that are available through the NLM. In most cases, the full text of the article is available. A tutorial is provided for those who might need assistance in accessing the material.
