Hi,
Wiley purchased a number of the Wrox books (along with the rights to the Wrox brand and website), but not all of them. It has been my understanding that any Wrox books that Wiley did not purchase from the liquidator were later purchased by APress publishers. If there is a topic you are looking for that you do not see here, then Wiley did not purchase that book.
Thanks,
