So Amazon is now selling "The Art of Electronics - Third Edition Improved. This version is expanded, with some new material and corrections, and is 1220 pages. The original Third Edition was 1192 pages. Anyhow, the original edition has the gold tag in the bottom right corner that says "Third Edition" whereas the improved edition says "Third Edition Improved. Well so I purchased it, and found my copy had some damaged pages. So I had Amazon send me a second one, but then I just noticed today that BOTH of them are just "Third Edition" and not the "Third Edition Improved even though that is what Amazon is advertising as for sale. So I am going to return both of them. I spoke to Amazon Customer Service via Chat and they said, "Thank you for bringing this issue to our attention, we will launch an investigation immediately," etc...they might really be serious on that, because earlier today, the book was available from Amazon directly via Prime shipping, but I just checked and now it is only available via Kindle or third-party sellers. I don't know if that is from me or not, but hope so as that means they are addressing it quickly. I told them that this is a major technical reference and expensive, so I want the most updated version.
As said though, I don't know if that is from me or not so when the book becomes available again, something to watch out for. Watch out for counterfeit copies as well from third party sellers.
