Besides the print edition, the dictionary is also available on CD-ROM (EPWING format), online, and in electronic dictionary and iPhone versions. Electronic dictionaries that contain the fifth edition are generally flagship models. They include the Canon Wordtank G70, the Seiko SR-E10000 (the first electronic dictionary with GG) and SR-G10000, and the Casio "University Student" series (XD-D9800 in 2012) and "Professional" series (XD-D10000 in 2012). The Sharp PW-SB2, PW-SB3, PW-SB4 and PW-SB5 models also contain the full Kenkyusha dictionary. For both Casio and Sharp at least, the dictionary is also available on an SD or micro SD card that can be purchased separately for certain models.
