The Sieve of Asclepius: A History of Navigating the Medical Literature, From Index to Algorithm

MedXY Editorial Team•Jun 9, 2026•Medical News

Systems for searching the medical literature have never been neutral retrieval tools; they encode assumptions about relevance, quality, authority, and use.
The transition from printed indexes to MEDLARS, MEDLINE, PubMed, citation indexing, and evidence-based search filters progressively changed not only access to information but also research visibility and clinical decision-making.
Commercial actors, including abstracting services, journal publishers, and the pharmaceutical industry, have long influenced what information was curated, disseminated, and prioritized.
AI-assisted retrieval extends a longstanding history of selective mediation in medicine, making historical literacy essential for clinicians who increasingly rely on algorithmically ranked knowledge.
