Good luck my friend.
Truth is, most would be in almost pristine condition, other than a mangled cover, or a missing cover on the Bono book. You see, (here James goes, showing off his inside information) the printers of the first edition of the Bono Book used a sub-par binding and even brand new, in the box books tended to have pages falling out of the binding. The entire first pressing was then repackaged with a spiral binding, because the pages could just be cut and hole punched, threaded into the spirals, and voila, the first pressing is saved.
Later, when Mike was looking to re-order, he found out that no one wanted him to abandon the spiral binding, because an unthought of bonus of the ersatz solution was that one could open the book to a page, and prop it up on a typing stand, and look to it as a reference while working. Students love this feature.
Too bad more schools don’t use Mikes book. They tend to shy away from it because is one of the most expensive electrolysis texts out there. It just also happens to be the best, in my humble opinion.
