• When not all the books in the series are the same height.
• When books change covers with editions so they don’t all match unless you buy the series in one go.
• When some books are hardcover and some are softcover and it doesn’t match but you can’t find another copy.
• When some covers are different in certain countries so you don’t get the main one which also happens to look better than all the other varieties.
• Basically just books.
• God damn them.
