For "receipt scanners," watch out for single-sided. You need a duplex scanner to scan books (unless you want to scan one side of the page at a time). Many basic office scanners are single-sided.
Other things to check: DPI limitations for duplex (sometimes it's different); customizeable page sizes (how does it recognize the page); color v BW scanning (if it's color-only, you'll get whopping huge scans for books), and does it scan to multi-page documents?
If you're satisfied that it can do the things you need it to, get one *that has a return warranty* so you can return it if you try it out and find it just won't work. (Maybe the rollers jam if you put in more than 10 pages at a time. Maybe it scans too light or too dark and it's not adjustable. Maybe it doesn't jam much, but when it does, you have to practically take the machine apart to fix it. Maybe it's horrendously noisy. And so on.)
