“In legal cases where medical evidence is utilized, finding the best medical evidence usually leads to the strongest arguments.” Introduction to locating and evaluating medical information in the context of EBM. Topics: • defining EBM • EBM importance to medico-legal researchers • using bibliographic databases for medical information research • using the EBM method for doing medical research • evaluating information retrieved • surveying reliable electronic and hard copy medical resources

PUBMED/MEDLINE/PUBMED CENTRAL
• PubMed = MedLine + (some) PubMed Central • MedLine records have gone through a comprehensive journal selection
process • PubMed Central (PMC)
• free archive for full-text biomedical and life sciences journal articles • repository for journal literature deposited by participating publishers, and author
manuscripts submitted in compliance with the NIH Public Access Policy and other research funding agencies
• free access is a requirement for PMC deposit, but publishers and individual authors may continue to hold copyright
• reciprocal links between the full text in PMC and corresponding citations in PubMed • Some PMC journals are also MEDLINE journals • Some PMC content, such as book reviews, is not cited in PubMed
