The most important entry I found in my physical copy of the 1911 Britannica is for Eavesdropping[0], detailing the original historical origins of the term and how it was thought about just before our modern era.

> Though the offence of eavesdropping still exists at common law, there is no modern instance of a prosecution or indictment.

Thanks for posting this resource, I've often wanted to share a link to this and other entries.
