What It Offers
The Imperial Library was built from the start as a .onion service — it has no clearnet equivalent and never has. Its collection covers fiction across every genre, non-fiction from history to technology, academic textbooks, classic literature and international-language titles. Search by title, author or subject and download in your preferred format.
EPUB is the recommended format for general reading — it works on all e-readers and most reading apps. PDF preserves exact layout for textbooks and illustrated works. Use Calibre to convert between formats.

Load Times
The Imperial Library can be slow — 20–60 seconds on the first load is normal. This is Tor routing overhead combined with the server’s .onion infrastructure, not a problem with your connection. If it fails entirely, try again after 15 minutes; the server experiences periodic downtime.
