Where do you guys books you can't find on Amazon ?

Lovely. Thank you!

I write an email to the author / tweet them and get a link.

Hmm Interesting. I'm not sure if it'll work for every book. But I see it definitely see it working for some books! Have you tried it yourself for any author/book ?

That's what I said in my earlier message; that I usually take this approach. Worked for a bunch of tech books, Christopher Paolini, Brandon Sanderson (spoke on Reddit),

I use these two websites - sanet.lc 1lib.in
