Physical media is the only way I retain what I read. I have no idea why, beyond just being an idiot.
I own a KOBO, a Kindle, I listen to tons of audiobooks but my retention via those routes is pretty awful. I figured at least having a big ass KOBO to read from would be close to a book.
I like the smell of a book. I like thumbing thru pages. I like the idea of flipping back thru a couple pages manually to reread something that confused me at first but got clarified a few pages later.
That really sucks that a used library book was 170. Is it something rare, out of print or something similar? Only books I’ve ever paid that much for were college textbooks that I couldn’t use an earlier edition for, or needed a stupid key code for testing access etc. 170 makes my pocket hurt and makes me sad.
