The name London Review of Books may mislead you. Ostensibly, the articles are book reviews, but barely. The books reviewed are more starting points into long-form articles on their subject matter. The articles are uniformly fantastic, though obviously not uniformly interesting to everyone. I find that every issue carries about three to five articles I find really interesting.
I‘ve just yesterday read an old LRB issue where in one article the book ostensibly reviewed was first mentioned after three whole pages!
