The book “Clouds of Secrecy: The army’s germ warfare tests over populated areas” by Leonard Cole is a mainstream academic account of US army’s covert attacks on American citizen in peacetime.

How to copy browser images hidden under layers of HTML
I wanted to use the image of the book cover in a cartoon but the cover had changed in its reprint avatar. It is not as dramatic as the original.
I tried to search for the book and Google and other search engines have lost most of the links to the book. Bing search engine used by DuckDuckGo returns on images of clouds, not the book. (This shows how believable Microsoft’s claims on on AI and such.) On Google, I found very tiny images of the old cover. However, one result in its Book search was humungous. This image could not be saved easily to desktop.. On examining the HTML using the “Inspect Element” option, the image was still untraceable. To protect the copyrighted contents of books, Google has already restricted the amount of content that can be viewed but even that content is obscured using obfuscated HTML/CSS DOM code. This is understandable because Google could be and had been sued by publishers over its book scanning service. Anyway, I wanted just the cover image. Here is how I accomplished it.
Select View » Page Info » Media and scroll down to the image you want to download. Copy the URL and paste it in a browser tab. Now, you can right-click the image and save it to your desktop.
