If you would like to buy a Leanpub book on behalf of a library, you need to contact the author directly to negotiate the purchase.
To contact the author of a Leanpub book, please go to the web page for the book on Leanpub, and look for a button that says "Email the Author(s)". This button can be found at the bottom of the "About the Book" section of the web page.
Please note that we do love libraries! Leanpub books belong to their authors, not to Leanpub, and we're simply letting our authors choose themselves, how to sell their books to libraries.
