In 1999, the Yomiuri shimbun released a CD-ROM titled "The Yomiuri shimbun in the Meiji Era," which provides a searchable index of news articles and images from the period. Subsequent CD-ROMs, "The Taisho Era," "The prewar Showa Era I" and "The prewar Showa era II," were completed eight years after the project was first conceived. "Postwar Recovery," the first part of a postwar Showa Era series that includes newspaper stories and images until 1960, is forthcoming. Issues of Yomiuri shimbun printed since 1998 are also available as an online resource through Lexis-Nexis Academic.
