Are there any good sci-fi books where this is explored?
Marshall Brain's Manna[0]. It goes into the recursive effects of "anytime anyone accesses information, that access is publicly logged" as well.
Though in my view the story hasn't held up very well over the past 12 years, compared to great scifi with similar tropes, such as Egan's Permutation City[1] or older Stephenson. In some ways that's due to a less intense writing style; in other ways it's due to parts that have essentially come true, making them seem retrospectively like "bad scifi".
Egan's description of mind-merging in Closer[2] might also be of some interest, as it explores the conceptual overlap between intimacy and real-time mutual information access.
