Does this count both templated and non-templated citations? Do you count citations appearing in any area of the article (e.g. inline footnotes, "references" section, "further reading" or "bibliography" section, and "external links"?) Or is anything left out? > Our top-line research questions focus on citations containing URLs, so we > broke down our results into citations with a URL (78%) and those without > (22%). > > The top 5 domains in citations with a URL are: > 1. books.google.com (73777 - 1.48%) > 2. news.bbc.co.uk (52347 - 1.05%) > 3. www.stat.gov.pl (51598 - 1.03%) > 4. www.nytimes.com (39454 - 0.79%) > 5. www.imdb.com (24993 - 0.50%) This will probably be part of your published results, but it would be very interesting to see a long-tail list of these domains, and maybe try and break them out into types -- that would start to get at questions like how many paywalled journals are cited, etc. > The top 5 types of citations without a URL are: > 1. cite book (190090 - 13.65%) > 2. citation needed (148339 - 10.65%) > 3. cite journal (63722 - 4.58%) > 4. cite news (25052 - 1.80%) > 5. citation (22773 - 1.64%) "Citation needed" is really the absence of a citation, not an actual citation, right? :) The others look like the standard reference templates.. so my question above about templates applies. > We have also looked at the *inequality* in citation domains.

Interesting!
