Both from downloading AND from self-counting, there's only 53 in each post. If the set cover is correct, there should be 54 NOT counting the cover/back (though Hegre is notorious for being in counting his own sets) so there's 3 missing. Or if the OPs are correct and there's supposed to be 57 but OPs usually don't count the cover/back either, and so there's 6 missing.
Any thoughts? Normally I don't care enough to say something, but I've decided I like the personality she shows, so I'd like to see anything that might be missing.
