Since I'm not really sure where else to ask this:
Maybe I'm missing something, but I've found so many problems in doing that without having to literally tear up the book by carefully dis-binding it and removing the individual sheets. Namely besides that, if I try to just use the book, I'm fighting the binding from it going closed, the size of it itself is awkward to handle, especially if I'm doing it as a diversionary activity out somewhere in public. Then somehow there's always ink transfer (like carbon copy) to the pages below when I'm writing along with the indentation on the paper providing a nice memory of past crossword solved and confusing the matter
So, am I missing something obvious? How do people typically handle solving crossword puzzles out of books so it's both convenient and not annoying to do?
