Indeed, there were times when Amazon was the only way to link to a book that had meaning to most if not all site visitors. These days the internet archive, open library and wikipedia function as a neutral resource that simply wasn’t available for many years. Similarly authors and publishers now have a web presence unlike ‘back then’. The only thing that still doesn’t have much meaning or creates much agency imo is trying to link to a different bookshop, as that specific bookshop probably can’t serve most of my blog readers. On the other hand, the indie bookshop around the corner is likely much less of data hungry kraken (except for G’s analytics) than Amazon is.
