Recently I gave a copyright release to a European professor who has a Phd level book coming out in a few months allowing him to cite and quote one of the articles I wrote and published on my site. The citation refers back to the url of the original article and mentions my name and the site name. From what I understand, my article is being quoted verbatim in its entirety. The topic of the book is highly relevant to my website. This is a professional/academic book and there is very little chance of it being published in an electronic machine readable format. It is also likely to be read in a very small niche circle. The publisher is John Wiley.
I have an informational/paid membership site based in US with global clientele.
I consider this a very authoritative citation and I am wondering if this is something that Google might consider as a quality signal. Or do they even have the ability to recognize the citation in print.
