A Way to Preserve Digital Books

Today, many libraries are only given an option to rent ebooks, from platforms like Overdrive.

Here's the vision we aim to build — together...

Build your Library

  • Lenny comes preloaded with thousands of open access titles
  • Easily import & secure your library books
  • Buy & import from openlibrary.press with 1-click

Lend your books directly to your patrons

  • Customizable digital lending rules
  • Use LCP & Thorium Web Reader
  • Analytics dashboards for engagement insights

Automatic up-to-date OPDS Feeds

  • Real-time metadata from OpenLibrary.org
  • Metadata is shared and fixed in one public place
  • Loads directly into Thorium, SimplyE, Aldiko Next, and more

A federated future for libraries

Imagine an world where every library is a critical destination in a unified, global network:

  • Lenny super-charges every library into a digitally sovereign, discoverable partner.
  • OpenLibrary.org helps us connect: empowering 11.5M million readers to find and borrow books directly from participating libraries.
  • OpenLibrary.press empowers authors and publishers to escape the walls of corporate platforms and securely sell DRM-free books.

Built to Ensure Library Futures

Lenny is the missing infrastructure libraries need to reassert ownership over digital books. Paired with OpenLibrary.press, libraries can now buy ownable books directly from authors and host them locally or collaboratively.

Discovery happens through OpenLibrary.org, which connects millions of readers to books hosted by libraries, returning traffic and trust to the public web.

With Our Powers Combined:

When you combine Lenny, OpenLibrary.org, OpenLibrary.press, you don't get a platform, you get a public utility for books. Lenny helps libraries retain their role as digital stewards of knowledge, while OpenLibrary.org powers discovery and access across the so patrons always find their next great read.
