How can I find out more about Ayn Rand’s intellectual and artistic development?
The best source is Miss Rand herself: read Journals of Ayn Rand and Letters of Ayn Rand. The Early Ayn Rand is a collection of stories and plays written by Ayn Rand in the 1920s and 1930s, and includes passages cut from The Fountainhead. See also The Art of Fiction: A Guide for Writers and Readers.
