Literary stock market

In preparation for updating the bibliographies at the site, I've been running some searches on various authors in the MLA bibliography. (MLA doesn't always have references to books, but it does catch most of the articles.) Here are the rough results:

• Henry David Thoreau: 3050 references
• Stephen Crane: 1248 references
• Edith Wharton: 1209 references
• Frank Norris: 517 references
• Sarah Orne Jewett: 350 references
• Frederick Douglass: 323 references
• Rebecca Harding Davis: 93 references
  
• Mary E. Wilkins Freeman: 83 references
• Frances E. W. Harper: 48 references
  
• Sui Sin Far: 44 references
