Beg to differ. Books are ipso facto the creation of one person, informed by their experience. They take time to write and reflect only specific concerns. They are microscope slides, not panoramas.

Magazines are contributed to by different writers with different experiences and views. They are immediate, must reach a wide market and absolutely must be up-to-the-minute in terms of what is going on. In terms of day-to-day life, they provide a far more accurate picture of the norms and expectations of society at a specific time.
