ADAHOONHILIGHII, or Current Events, was developed by educators as a tool
for teaching Navajo language reading skills.  It was a monthly newsletter
distributed to reservations and posted on bulletin boards.  It covered
both local and national events.  The first issue was published August 2,
1943.  In the late 1930s, author Oliver LaFarge and anthropologist John P.
Harrington of the Smithsonian Institution devised a Navajo alphabet that
was usable on an English typewriter.  Until that time, a written language
had not existed.  The so-called "Harrington-LaFarge alphabet" was refined
by Dr. Robert W. Young an Dr.. William Morgan, and was the language used
in ADAHOONILIGHII.
