You are hosting a journal club on chest pain management in the emergency department (ED) for colleagues and trainees in your department. Interested in understanding the history of cardiac biomarkers to evaluate ED patients with chest pain, you search PubMed using the combination of terms "cardiac biomarker", "chest pain", and "emergency department". Your search nets no studies prior to 2002 which you doubt is accurate, so you take the old-fashioned approach and start flipping through the oldest issues of emergency medicine journals at your local medical school library.
