Everyone is afraid of what they might be missing on the internet, but few of us know what’s missing from the internet. Blacklistsis an encyclopedia of restricted websites, in 13 volumes of 666 pages each.

Blacklists contains over 2 million websites compiled from lists that are low-cost or freely available. The collection represents just some of the traffic that is considered illicit or inappropriate by those who have the tools to regulate it. Whose rules and which cultures decide what we see on the web? By browsing through these books, you’ll have a small peek into the internet you don’t see.
