You're right on both counts! Sorting cards is indeed fun, as is any tiny universe on which one can impose order. And yes, I'm into the physicality of books as well, so book series are best when they match. In that way, I can always appreciate coming across a series complete, so that I can read it and collect it as a matched set. (This rule also applies to non-sets as well; I have three complete sets of Jane Austen, and one of my prized inheritances is from a beloved family friend, who gave me her mother's books, including complete turn-of-the-century sets of Maupassant, Dickens, and Robert Louis Stevenson, among others.)
