This book is unique, covering a topic pretty much overlooked by other historians of space programs and policy and I tried to make it a good read as well. If you work for a library or are affiliated with a college or university in any way, I would appreciate you recommending it to the library's acquisitions staff. Libraries have to learn about it in order to know it exists and then acquire it, so recommendations are helpful.
If you would like to acquire it yourself, the link to the book is: https://upf.com/book.asp?id=9781683402602. If you wait long enough, the heading just above it will cycle around to the discount code for history books. (It's their spring sale.) You can also order it on amazon.com but buying it from the publisher is more fun.
