One of my favorite books in elementary school. Checked it out from the school library several times per year. Now I grab a copy just about every time I see one, think I've bought three—I have kids now, and because of the format combined, now, with the age of the book, the binding tends to fail, so they're a bit consumable at this point. I've lost one so far. IIRC from when I looked into this a while back, there are actually two versions of the book, and one has more pages than the other (like, a dozen more, or perhaps twenty) so if you pick one up and are like "I could have sworn..." it might be because you're holding the one with less material, and are used to the larger one. I noticed and did some digging because I flipped through a digital version on archive.org and it was missing some stuff that (at least) one of my physical copies has. I forget whether it's the earlier or later edition that has more material.
