@WDB I have added the missing one and tried to find correct images. Seeing the difference between normal cover and one with raised lettering proved difficult so I went with what I found.
Feel free to include (better?) images for these two so we can add them to Core. Thank you for letting us know.
I don’t think it matters that much. I do think you have the images reversed. 2014,9781608871858, is the one with the raised silver logo but hard to tell in a photo. I took a bunch of images but not sure they are any better. It looks correct when I take the picture but crooked when I crop. Here is a front and back of 2014.
