Sarah Hoyt's "20 Things You Might Not Know About RAH"
Sarah Hoyt's multipart biographical series on Heinlein. This is excellent, in that it's bringing Heinlein to a website that gets thousands of visitors a day.
The material will be familiar to most of us here, especially if one has read the biography, Part I (which she acknowledges and links). You can access the on Hoyt's page at PJ Media.
