Book Directory The Knowledgerush.com book directory is a catalog of free books available on the internet. It's a community effort and we're hoping that you can contribute by helping us find and categorize books. To add online books to the directory just use the book submission form, the submit new book link that's on each of the directory pages, or send us an email with the Author, Title, Category and URL. We'll include any book that can be downloaded or read online for free. Aspiring authors may submit links to teaser short stories to generate interest in their for profit work. All submissions will be reviewed before they are added to the catalog. To post articles, poems, or links use our community pages.
