In the 1960s, the Cherokee Phoenix Press began publishing literature in the Cherokee syllabary, including the "Cherokee Singing Book". A Cherokee syllabary typewriter ball was developed for the IBM Selectric in the late 1970s. Computer fonts greatly expanded Cherokee writers' ability to publish in Cherokee. In 2010, a Cherokee keyboard cover was developed by Roy Boney, Jr. and Joseph Erb, facilitating more rapid typing in Cherokee. The keyboard cover is now used by students in the Cherokee Nation Immersion School, where all coursework is written in syllabary.
