X All The Y

You don't really call a phone book a "book" tbh...
You also don't call a hymnal a "book" :/
I don't think it would really be referred to one, imo :]

What about Guinness world records?

Hmmm...
Ig it counts :P

Well according to my parents neither do 😭😭 i have wasted more that 3 hours

😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭

Yeth

by this definition, I believe a phonebook can be considered a book

no, it's just definitions of words... but it you could call it a nonfiction book about the english language :/
