Just a thought to those who ask for discounts on this edition if owning the first edition. If you held the hard copy of the 1st edition book, would the bookshop give you a discount on this 2nd edition? I'm happy to see such works updated and available. The advantage of digital to me is that corrections and typo errors are able to be fixed and updated without cost unlike the hardcopy which remains with those issues. Whole new editions are a different thing entirely.
- Agreed. I just want to know how much the 2nd edition adds to the first to make it worth full or discounted price. Sometimes 2nd editions are merely a few word changes and syntax updates.
