A bibliographic database containing older medical literature citations, typically pre-1966 MEDLINE entries. Part of the historical medical literature indexing system.
Compound of 'old' (Old English eald) and 'MEDLINE' (Medical Literature Analysis and Retrieval System Online). MEDLINE itself was created in the 1960s by the National Library of Medicine. OldMEDLINE specifically refers to the retrospective digitization project covering earlier medical literature.
OldMEDLINE represents the fascinating challenge of digitizing pre-computer medical knowledge - it required manually converting decades of card catalog systems into searchable electronic databases. This project essentially created a bridge between analog and digital medical information systems, preserving centuries of medical scholarship for modern researchers.
