Abstract
Headlines and resumes of industry and company reports taken from the Nihon Keizai, Nikkei Sangyo, Nikkei Ryutsu and other Nikkei newspapers are computer-stored in kanji mode and the newspapers from which the reports are taken are microfiched. The stored items form a system NEEDS-IR retrievable by descriptors in four categories, company, merchandise, operation, and locality. The author details the value of news items for retrospective search purpose and the highly structured retrieval vocabulary system.
