Due to the U.S. Supreme
Court Daubert v. Merrell Dow Pharmaceuticals, Inc. decision in 1993,
peer-reviewed medical literature became greatly elevated in importance.
It should be emphasized, however, that peer-review systems among
journals are not standardized, and reviewing practices and
vary widely. And there are many limitations and shortcomings of the
peer-review process as well, pointed out in a 2007 article published by
Susan Haack in the Stetson Law Review, Vol. 36, entitled Peer Review
and Publication Lessons for Lawyers. that can be downloaded from here. All of that said, here are some pointers on locating peer-reviewed
Unarguably, the best source in the United States for locating authoritative medical literature is the MEDLINE database produced by The National Library of Medicine, searchable free of charge at PubMed. Unfortunately one cannot restrict searches at PubMed to peer-reviewed journals. However the great majority of the journals indexed in MEDLINE ARE peer-reviewed and must pass a rigorous review process to be included in the database.
A journal's Website or its sponsoring organization's Website should indicate if a particular journal is peer-reviewed. One sometimes has to navigate a bit to find this information. Also the first pages of a peer-reviewed copy of a print journal will likely state that fact.
Two well-known databases, available at many libraries but not accessible to individual subscribers, allow one to restrict searches to peer-reviewed journals:
Ulrichsweb: Global Serials Directory. Ulrich's uses the term, "refereed," however, instead of "peer-reviewed."
CINAHL (Cumulative Index to Nursing and Allied Health Literature) has a limiter for searching only peer-reviewed journals. Nearly every hospital library subscribes to the CINAHL database, but unfortunately, most don't offer it to the general public.
Good luck in determining if
that journal is peer-reviewed. If located through a PubMed search, know that it
