Worldcat is my bestie and my one true love!! Not only does it tell you what library a book is at, but it also price compares different used book sites against each other for easy view! It's how I got Tarot For the Master for $10!!
Oh, and since I have your attention: z-library (books and textbooks) and sci-hub (gatekept scientific journal articles.) I just ripped a textbook for class off z-library and snatched a required reading from sci-hub. Life is good and education should be accessible at every stage and station of life.
