摘要

The first-generation ABC storage and retrieval method, an HDL-developed method that utilizes appropriate standardized English-language statement processed and printed by a KWIC-type computer program, was subjected to a performance test. The test was performed with the primary objective to spot deficiencies and to develop the second-generation ABC model. The results are briefly reported. The improved model is characterized by descriptors of unlimited length, the introduction of facets or microschedules that produce logical organization of documents under important keywords, and a decrease in the number of verbalized concepts. Type of document, level-ofdifficulty descriptions and operating parameters of equipments (a feature of the ABC method are transferred to card catalogs. (Author)
