 family), native to Europe and Asia. It has luxuriant foliage and large white or pinkish flowers; in the wild state it is sometimes thorny. The medlar has long been cultivated in parts of Europe for its acid, apple-shaped fruit. It is usually not picked until after it has been touched by frost; then the fruit is stored until the ripening process is completed. It is commonly eaten fresh but is sometimes used for preserves. Medlar is classified in the division MagnoliophytaMagnoliophyta
, division of the plant kingdom consisting of those organisms commonly called the flowering plants, or angiosperms. The angiosperms have leaves, stems, and roots, and vascular, or conducting, tissue (xylem and phloem).

Jenkins' discussion of the time-consuming process of failure analysis sheds additional insight into the painstaking and thorough nature of Lancaster's work on the MEDLARS evaluation.
In a January 1967 memo to the NLM director, the associate director for Intramural Programs wrote the following regarding early case reports from the MEDLARS evaluation:
We have begun preliminary analysis of test searches from the MEDLARS evaluation program.
Lancaster continued to work with NLM on vocabulary control, looking ahead to plans for the online environment of MEDLARS II.
Training Programs Following completion of the MEDLARS evaluation, Lancaster was named deputy chief of the Bibliographic Services Division in February 1968, then special assistant to the associate director for Library Operations in September 1968.
The critical evaluation of MEDLARS searches conducted by Mr.
We are now looking to MEDLARS II and, on the basis of this report, we should be nothing but optimistic.
Of the MEDLARS evaluation, Lancaster (Lancaster & Gillespie, 1970) discussed it as the first major evaluation of a large national information system and noted that Cleverdon (1968b) had already utilized its detailed examples for a paper on procedures for evaluating a retrieval system at various stages of development.
In the chapter on Information Science Applications in Medicine (Caceres, Weihrer & Pulliam, 1971), the authors write: "These evaluations of MEDLARS as a model will be most helpful in the implementation of future systems" (p.
The MEDLARS evaluation was important at one level because it was the first comprehensive evaluation of the first large-scale operational information storage and retrieval system--two very powerful firsts.
Lancaster conducted a second evaluation of NLM's MEDLARS retrieval system in 1970-71, this time for its innovation as one of the earliest online services.
One disadvantage of the MEDLARS Demand Search Service was its slowness.
