Over the next months I read it. It was very interesting! And then I got a reminder of Stephen, the chap who had asked me. Was I ready to upload? So I finished it off and tried to upload it. Generally, if you are asked to review something, you just login to the site of the publisher (Elsevier in this case) and all your tasks appear. If you have a manuscript in review it will be there, if you have been asked to review someone else's article it will be there, and there will be 'action buttons' and you can click them and then you can perform an action such as uploading a revised version of your manuscript or a review of the other person's manuscript. But there was nothing there! I pressed the 'help' button.
A few days later I received an email. They were not sure what I was referring to. I had given the name of the journal (well, the abbreviation anyway) and of Stephen and I supposed that would do the job. It didn't. They thought I was reviewing an Elsevier book, instead of a random book (by Wiley, since you ask) for an Elsevier journal. Telling them repeatedly didn't help. They even denied Stephen had anything to do with Elsevier. This was going nowhere! Contacting Stephen himself revealed in the end my document didn't count as a review, but as a manuscript, so I had been looking in the wrong place. It wouldn't come up in a list; I had to just submit it as a manuscript. Uh, OK! And of course I quickly got a confused response; could I submit a reference list with my submission? A reference list? Since when does a book review need one? But at least that was resolved by only one email. Finally it was sorted! And now I hope my review will be of use to people. It was interesting to do!
