Purple Sage Indexing professionally prepares back-of-the-book indexes that are comprehensive, accurate, and delivered on time for general interest books, scholarly books, and textbooks.

We can index almost any topic, but we specialize in:

  • economics
  • political science and public policy, with a particular focus on left-wing politics and socialism
  • religion, theology, and spirituality
  • history and culture, especially that of the American West
