total to over 220,000. The CD-ROM version was published in 1993 and revised with color illustrations (like the Nihongo daijiten) in 1996. In 1992, Iwanami published both an e-book format 4th edition and a useful Gyakubiki Kōjien (逆引き広辞苑 "Reverse dictionary Kōjien"). 5th edition The 5th edition (1998) includes over 230,000 headwords, and its 2996 pages contain an estimated total of 14 million characters. Iwanami Shoten currently publishes Kōjien in several printed and digital formats, and also sells dictionary subscription services for cell phone and Internet access. Various manufacturers of Japanese electronic dictionaries have licensed the digital Kōjien, and it is the core dictionary in many models. Shinmura's preface to the 1st edition stated his hope that the Kōjien would become regarded as the standard by which other dictionaries would be measured. This has largely been fulfilled; many people regard the Kōjien as the most authoritative Japanese language dictionary on the market. It remains a bestseller in Japan. According to Iwanami, the 1st edition Kōjien sold over one million copies, and the 5th edition brought cumulative total sales to over eleven million in 2000. 6th edition The sixth edition was released on January 11, 2008, includes more than 10,000 new entries, bringing the total to approximately 240,000. It also contains an additional 1,500 quotations. 7th edition The seventh edition was released on January 12, 2018. Changes include 10,000 new words were added from 100,000 words collected by its editors firstly, including "apuri"(app), "Isuramu-koku"(Islamic State), LGBT, "hanii torappu" (honey trap), "jidori" (selfie) and "diipu raningu" (deep learning). Other changes include citing available source literature for a given explanation of a term, listing changes of the usages of a term, addition of 140 pages without adding book thickness. However, the definition of LGBT in the edition was written as "individuals whose sexual orientation differs from the majority." Some criticized that the definition only describes the "LGB" portion of the acronym which refers to sexual orientation, while the "T" refers to gender identity.
