I read the Audiobook version of this book. It presents a narrative of the development of the very early stages of the internet. I enjoyed it. I think it would also have been fine in print or ebook formats. It is not too long and seems to present the events in a mostly linear fashion.
You'll get a great overview of the names, organizations, and machines that were used in this period.

Kindle edition sells to US-only accounts though, which is a bit annoying :-(
[1] The Kindle version + Audible upgrade is nearly always cheaper than Audible alone. Not sure why.
