Note that the statistics below count the number of publications associated with publication-level authors and editors. They do not count the authors of individual titles (stories, poems, etc.) contained in publications. Each edition of a book increments its author's count. Different forms of an author's name, e.g. 'Mary Shelley' vs. 'Mary W. Shelley', are counted separately.
