Ask HN: How do you decide a non-fiction book is worth your time?

#1
Books, especially non-fiction books, are big investments in terms of time and attention.

Before I came across a book called "How to Read a Book" [1], my philosophy was to simply to read book that's recommended to me and simply finish it - there must be something from the book that is of value. After reading HTRAB I realised that time spent reading a bad book is time not spent reading a good one. Thus I want to be better at assessing a book before I actually decide to read it.

"How to Read a Book" also suggests "Systematic skimming", which involves (some personal steps in the list):

- Reading the preface

- Reading the Table of Contents

- Checking the Index - Searching for a topic I might know a little bit about, and checking what the book says about that topic

- For books that rely on research (most (pop)sci/political books), I usually check the quantity of sources at the back of the book - however I am not sure how to check for the quality of those sources. I wonder if there is a website where I can put in ISBN and it gives me a "sources quality score"?

- Skip to a random chapter, read a page or two

- Search stackexchange/HN if for any mentions of the book to see what other people say about it

- Look up Author(s) and what they are about

What do you think? Any suggestions, additions to this list? How do you decide it?

As I'm far past my student years I don't _have_ to read certain books. So nowadays I read non-fiction the same as fiction: I read until the book doesn't hold my interest anymore. I don't feel compelled to have to finish a book. As you said, not reading bad books (or good books that are just not for me in that moment) leaves more time for reading other books.

I buy enough books, but I mostly read books from the library. Wonderful institutions, those are. Don't like a book? Just return it and get a few others.

Having a set of "cool" words or definitions and "anti-cool" one. Having a hope that some special topic helps in the research. Also unlike with fiction books, it is very typical to read about some narrow thing, maybe few pages, and to consider the book as a read because of some achieved goal.

I mostly go by a) recommendations from people I trust b) reviews (that I mostly find in the dailies).

Also, if you focus on classics I think you’ll be fine. I.e. Hemingway, Kafka, Dickens et al. Classics can have their flaws too, but I think we can assume they didn’t become classics by pure chance. So IMHO it’s a reasonable filter.

I usually get new book ideas from other books, maybe it's a reference to an author or a quote. This has been great for staying in the topic. Another similar source are articles I read online, specially the ones that look well researched.

A site that has been a great source for ideas is https://www.themarginalian.org/ by Maria Popova. It's so well written and she usually brings together different books that are somehow connected by the topic of the article.

The last post is a list of the best books for 2023, a lot of non-fiction https://www.themarginalian.org/2023/12/19/favorite-books-of-...
