Random thing: if you’d prefer not to support Amazon, a popular alternative is linking to listings for books on bookshop.org (though I don’t know how their affiliate referrals compare).
e.g.:
Lenin, _Imperialism: The Highest Stage of Capitalism_
https://bookshop.org/p/books/imperialism-the-highest-stage-of-capitalism-vladimir-lenin/10471387?ean=9781913026028
or, a shorter version of the link:
https://bookshop.org/book/9781913026028
(It seems like the shorter link just has the ISBN.)
