The concept of MEDLARS as a publication/retrieval system was the product of several forces operating during the fifteen years prior to 1961. These included the overriding imperative of medical index publication, the Welch Medical Indexing Research Project, a drive to master the theory of medical subject headings, the innovative impact of coordinate indexing, and the confidence produced by the success of the Index Mechanization Project. By virtue of this experience, MEDLARS became a prime example of a well-understood enterprise seeking a computer application, a circumstance which augured of its success.
医学文献分析与检索系统（MEDLARS）作为一个出版/检索系统的概念，是1961年之前15年中多种力量共同作用的产物。这些力量包括医学索引出版的首要紧迫性、韦尔奇医学索引研究项目、掌握医学主题词理论的努力、组配索引的创新影响以及索引机械化项目成功所带来的信心。凭借这一经验，MEDLARS成为了一个对寻求计算机应用的企业有充分理解的典型例子，这种情况预示着它会取得成功。
