Hello @Spinningspark: Regarding the category Pages with DOIs inactive since 2014 that appears on this page. When I Google 10.1044/1059-0889.0701.05 it finds [1]. Admittedly, you probably know more about this than I do, so could you please explain what's broken? Thanks, JMHamo (talk) 02:04, 7 November 2015 (UTC)[reply]
I don't know any more, but the doi link is definitely broken. You are right that it does not seem to be an editor error at Wikipedia, it is more likely upstream of us. It might be AJA have published the wrong doi or have not registered it properly, or it might be a fault at doi.org. I have used the fault form to report the error. In my opinion, dois are more trouble than they are worth. SpinningSpark 08:29, 7 November 2015 (UTC)[reply]
