An information retrieval system has a search history storage for storing information of the relation between a search condition entered by the user and selected paper data. In the search history storage, information of the relation between the search condition and a detailed search condition is also stored. The selected paper information and the detailed search information is updated on the basis of a screen transition instruction. The selected paper information is used for a searching process in a search engine and a screen generating process in an HTML document generator.
