Thanks to all who let me know that most of the reviews in Book Briefing had vanished. The technical issue responsible has, I hope, been resolved. The plan now is to restore the more than 500 reviews which were lost. I still have all the draft versions. The challenge is to edit them all again. That might take a while, so I have to ask for your patience. I think it's worth reposting the reviews as many of the books were published long before the Internet became popular. At worst, some of the reviews may save you wasting money.
