Excerpt from this article:
For a time, it seemed that eBooks and kindles would displace their physical counterparts, but this didn’t quite come to pass. Like the recent revival of zines, the encroach of digital has resulted in a renewed appreciation for the physical – and beautiful. Part of this has been in direct response to eBooks; a tactic to boost the sales of physical books is to remake them as desirable objects, and a way to make objects desirable is, of course, to make them aesthetically appealing. But social media – specifically Instagram, which promotes the coveting of beautiful covers on hashtags such as #bookstagram – is putting a new emphasis on cover aesthetics. We no longer need to go home with someone in order to see their bookcase.
