Possible, google is deep state and some of the books listed seem to be alien/shill distractions. However most of the books are relevant (covering satanic cults, terrorism, Middle East policy, corruption, etc..) One shill tactic of clowns is to present 80% truthful/relevant information then sew 20% bullshit into it in order to muddy up the truth. This google books search topic is just something to be aware of I suppose, whether it is legit or a shill operation.
