This checklist focuses on not buying junk/scam books. I read it because I'm interested in buying good books, those that I want to keep on my bookshelf, will use frequently, and would recommend to friends. This post doesn't help with that.

Also, the post discriminates strongly against self-published books. While this may be a simple strategy to avoid potentially scammy books, the potential sacrifice isn't worth the benefits to me.

Also, there's a typo at the end in It really feels like hard word to choose a good book - s/word/work.

Thank you, typo fixed.
