"the really rather wonderful Life After Life..... Surely you don't just have to rely on visual clues and hearsay - you could try Goodreads, for example"
You see, that is why Goodreads is useless - there are people there (like you here) who feel Life After Life is really wonderful and that is very far from my perspective. Recommendations only mean something if you know the person who is giving you the recommendation - what her tastes are, the kind of books she reads, etc. So, if I have graded 3 friends on a scale of 1 (totally unlike my taste) to 10 (very much like my taste) and three of them have given this book 5, 3, and 2*, I can take a weighted average of their ratings:
[(2 x 5) + (5 x 5) + (9 x 2)] / 16 = 3.3_ More useful to me than the arithmetic average 4_ which is all I'd get from Goodreads and Amazon. We all do a vague version of this calculation in RL - i.e. give more importance to the recommendations of friends who read/like books we read/like.
"Sense and Sensibility and Wuthering Heights wouldn't have made the cut if you were to maintain a policy of avoiding debut novels by female authors"
It was extremely difficult for a woman to be an author and be published at that time, so the odds were actually quite good that any novel by a female author would be extraordinary. You see where I'm going with this.
"while describing a novel as 'life affirming' is a lazy review cliche, my experience of reading much great literature (and I use the term advisedly) has been just that."
Heart-warming and life-affirming, I find, is what book "critics" in women's mags etc say when the book doesn't actually have any merits that that would appeal to a reader like me - not literary, not intellectual, not challenging, not edgy, not new and different (for me).
