Yes, the standard of books dropped considerably during the last year. I have over one hundred Wrox books. It was very annoying to fork out c £50 for Professional C# and then find over one hundred errors in it. Nor was I pleased with Wrox's "We'll correct them in the second edition.". If they offered it half-price I would have bought it but I was sorely tempted to try returning it as "Unfit for purpose".
I acted as a Technical Reviewer myself for Wrox. The pay was low but I would have done it more except they stopped using them towards the end, perhaps they were struggling to pay them.
To be fair I also own a few Wiley books. One particular one about building Instant Messaging applications takes the record for appalling quality control. The font set used replaced many punctuation marks with empty squares, the proof reader and editors comments to the authors are still in the text and the code sample have many typo errors as well as the code being of dubious technical merit. It was the worst advert ever for the development team that wrote the application featured, I wouldn't dream of using that firm.
I hope future Wiley/Wrox books will be better.

Good luck to you all.
