Whilst I don't agree with your reasoning, I am happy to add my "reference" to Further Reading rather than References. It is not really self-promotion to add an worthy but out-of-print book as further reading for those interested in the subjects. Certainly less self promotional than some of the press references which are basically just PR releases given spurious credibility by being recycled in the mainstream press. Sadly, much of what passes for journalism today is just PR stuff, which begs the question of how seriously we should take a lot of references!   

Well I might dabble in such edits, if I had more time. To be honest, I don't give tuppence whether my books are mentioned or not. It is of no advantage whatsoever to me, commercial or egotistical. I merely thought I was helping but clearly have transgressed Wiki's arcane guidelines, often inconsistent from what I can see. And to be honest, I do believe that people may have used my book without true attribution, there are one or two things mentioned that are so obscure that it would be rather a coincidence if they hadn't been read first in my book. Hopefully I'll not be tempted to dabble in Marmite, of which I know a great deal!  

thank you for your comments and help. not meaning to be argumentative, but I do like to get things as straight as I can. One more thing
you may be able to help with. a early drafts of a couple of my articles were tagged as lacking references - but although I've since added some very good ones from university text books and other mainstream publications, the yellow sticker is still at the top of the page. How do I get rid of it?
