About
Hi, I'm Raja.
I read 70+ nonfiction books a year, and I run The Useful Library to answer 1 question about each of them: what can you actually use from it this week?
Most books are 1 good idea wearing a 300-page trenchcoat. The Library finds that idea, tells you which chapters carry it, and gives you 1 step to try today. I write from Chennai, India, under The Useful Life, part of The Useful Media Co.
How the Library works
Chapter verdicts
Every chapter gets Read, Skim or Skip. Read means the chapter carries an idea you can use. Skim means 1 rule hides in a lot of stories. Skip means it won't change what you do tomorrow.
3 fixes from 3 books
Problem pages pick the 3 books that fix the problem in different ways, so you can choose the 1 that fits your version of it.
30-day tests
You can test any idea for 30 days and tell us if you kept it. Reader results appear once enough readers finish. Nothing on this site shows made-up numbers.
How it makes money
Some book links are Amazon affiliate links, and I sell a few reading tools like the Read to Transform journal. No publisher or author pays for a verdict.
