This post is just an array of interior photos from a high-quality architecture magazine called Dezeen. The photos below are the first ones I noticed after April 2015 that show bookshelves. There were also a few pictures that show books outside shelves. I didn't include those; this is about how bookshelves are depicted in modern architecture photos, not books.
Books and shelves might seem rare in these houses, but I don't think that reflects reality: There are even fewer TVs and laptops than books so clearly the photographers are choosy about where they point their cameras. No, what these pictures illustrate is how bookshelves are depicted in 2015.
Most of these are private homes, some are other buildings. Two are actually libraries (as is this). Each picture is a link to the relevant article on Dezeen. The top left photo is the one that made me start collecting notes.
