In addition, Heinlein was guest of honor at a number of smaller conventions for which his remarks were often not preserved. In 1976 and 1977 he accepted many such offers as part of his campaign to recruit new blood donors, but when his health deteriorated in 1977 he was forced to cease the practice.
