These books help with the “lead” part: they help with things ranging from organizing better meetings to getting buy-in for a significant change. I assume most technical leads are already technically competent, so only one of these books could be called “technical”.
This is not the first list of books to be published on the topic. There are many others like it, but this one is mine. I found these books to be useful after I was first promoted to the Technical Lead role, and even more helpful when I tried to improve the rest of the organization around me.
