Still reading my sci-fi, but I've done a brief diversion into book related model making that I thought could go on this thread.
Since
I mentioned it over here, I thought I'd post a few pics of the repair details on a hole punched copy of Chapter Approved. So it arrived in the red folder, the front and back cover had previously been glued to the folder with dabs of glue in the corners. That proved difficult to remove cleanly so I ended up mostly leaving it in place.

The covers were of course cut down somewhat in order to detach them from the original spine, the original spine was long gone. The first few pages in the binder were also cut narrower than the rest - which looked like they had simply detached originally from the spine glue.
I ws never going to be able to do anything about the punched holes, but I thought I could probably turn this back into a book again...
I should have done some WIP shots, but in essence for the bulk of the pages I clamped them along with some wax paper between two blocks of wood so they were tightly bound and the original spine edge was exposed (along with the wax paper to stop the glue sticking to the wood). I used an archival PVC (supposed to be fully neutral and has a longer flexible lifespan) glue along the edge, re-enforcing it with a bit of gauze. Once dry I trimmed off any excess glue.
With the pages and covers that were too narrow I glued on some
washi kozo tissue paper along the edges overlapping the page by about 3/16". This was alway going to be annoying as this would be a visible repair, but there wasn't much that could otherwise be done. The tissue is very thin, but strong so doesn't really impact the thickness. I trimmed the excess tissue off the top and bottom of each of these extended pages.

I then bound my extended pages and the front and back cover onto the spine of all the other pages. At this point I had a complete book, but missing the spine.
Fortunately I have a copy of Chaper Approved in better condition so I scanned the back, spine and front of that and stitched those together filling in the missing bits in my photo editing software. Then printed the resulting wrap out. Colour was never going to quite match. I trimmed the printout down and thought I'd got it right, but evidently mucked up a bit and my final result wasn't quite spot on with alignment on the actual spine itself. Still I left it for now, I might replace it one day if I can bothered. Still at a casual glance it passes quite well.

Much like rescuing an old miniature from ebay it's quite nice restoring an old book back to something like its original state.
