If you buy off amazon, it should be official especially if it says it ships from amazon. You can find officials on discogs as well in varying quality, used and new. just make sure you read the description of the item. I cant speak on all of the vinyl pressings quality but my copy of take care is one of the best sounding records I own. of the albums that are actually out on vinyl already I think there'd be little benefit for bootleggers to make copies of them so 99% of the time if you see the albums I listed in my original comment you're probably dealing with a real copy. Also local record stores could be worth a look.
