Via The Millions:
...for a ninth year, some of our favorite writers, thinkers, and readers will look back, reflect, and share. Their charge was to name, from all the books they read this year, the one(s) that meant the most to them, regardless of publication date. Grouped together, these ruminations, cheers, squibs, and essays will be a chronicle of reading and good books from every era.
So far, the writers included are Stephen Dodson, Ben Fountain, Emma Straub, and Jeffrey Eugenides.
There are also links for the past nine years of this as well.
