I hadn’t necessarily expected to read every word of the Lowell biography, but … it’s one of those books you thrust on your partner with an incredulous cry of “This is me!” [Nick Hornby, The Polysyllabic Spree, p16-17]
That is exactly how I feel about many passages in this journal of Hornby’s own reading, and I’ve only read the first ten pages! (I’ve read several Hornby books and haven’t been disappointed: About a Boy, How to Be Good, A Long Way Down. Good was the least good, but even that had value.)

I find Nick Hornby a bit hit and miss and, for me, his later books have drifted into sentimentality. But High Fidelity remains a brilliant read. Definitely my favourite of his and well worth reading if you enjoy your music. Slightly spooky though if you keep your records in alphabetical order and are called Rob
I agree on heterogeneous quality but not sure on the timeline. I loved A Long Way Down despite the sentimentality. How to Be Good not so much. I haven’t read High Fidelity but loved the film. Will get to reading it at some point, no doubt.
