For the "take a badly damaged book apart and put it in sheet protectors in a binder" trick. This is quite obviously a method of last resort. But it's turning the book I'm scanning now from "I'm going to destroy this book to scan it" to "I will have a perfectly usable reading copy- reference copy if I ever need to rescan" that I can enjoy without worrying about destroying whatever is left if I try to read it again.
Too often we get the hype on high grade books, or preserving what condition there is at the expense of not being able to enjoy what we have. Thank you, Jim, for reminding us about what's important with these books, and giving us a practical solution to those falling apart copies.
