It's an excellent resource. The copy I have was published in 1949, not 1986. According to an article in The Seattle Times (Tuesday, Nov. 5, 1996) a sequel was planned by the current students of Cleveland High School. In January, 1999 I communicated with Georgia Kumor, the school lIbrarian at the time, who said she expected to "wrap it up this Spring". I don't know if it ever was completed.
