For example, I like:
- Greg Egan - Ted Chiang - Nabokov - Kerouac - Ishiguro - Vonnegut - Bukowski - Kundera - Joan Didion - Oliver Sacks
Surely if you get a list of favorite authors like this from a few hundred people, you could trivially recommend new authors to people?
Specific author recommendations.
The related-books adverts at the end of many books.
Literary magazines within genres of interest.
Book reviews: NY Times, London Review of Books, LA Review of Books, New York Review of Books, Kirkus Reviews, etc.
Catalogues. Worldcat's been considerably enshittified in recent years, but remains useful. Open Library is increasingly appropriate.
ZLibrary's recommendations tend to be surprisingly useful, though it's harder to access these days.
Whenever I want to save a recommendation I just add it to Pinboard, with the tags ‘book’ and ‘wislist’.
So when I feel the urge to order new books I just look at those tags and order some.
* Hacker News Books - https://hackernewsbooks.com, the weekly most mentioned books on HN
* reddit reads - https://www.redditreads.com, the books that Reddit users are reading
* Shepherd - https://shepherd.com, the book recommendations from authors, creators, and experts.
I found interesting books from blogs sometimes.
