Every issue was like that -- full of little nuggets and gemstones. If you missed it the first time around, you should give yourself a treat. These are available as collections -- each volume has four issues -- and are available in hard copy or electronic PDFs. I just picked up a couple of the PDFs because when I'm working on Space: 1889 stuff it's a lot more convenient to have all the reference material on my hard drive than it is to haul around a bunch of books and still never have the one I need when I need it. You know what I mean.
