I saw in another comment you are in NY. Aside from what others have already suggested, you could browse in the Taschen book store or the Kinokuniya book store. They both have tons of photo related stuff to look through. Also, try going to a magazine store, there’s usually tons of photography themed magazines to look through. You could also just google something like photography galleries NYC & go check out random galleries. If you are in NYC, that is basically the epicenter of America to view photography, so you really have no need for social media to inspire you.
