wheatpaste will do just fine, that's flour in hot water, left to sit until it cools - you want to stir it of course for even consistency... then use a broad brush, put a thin coat on the back, slap it up, press the air out, and put a thin coat on top. Let dry... it won't be coming off, anytime soon.

I'm thinking I need to leave a bunch of these all over my library shelves.
Seen that... I'm after the actual stickers you can buy and get shipped.

Nice. Thanks for the tip.
