For their article on small world networks, Watts and Strogatz cited 27 sources.  Interestingly enough, a lot of these sources were in the biology field.  Many sources, in turn, cited this article (8,749).  The top 3 authors were G.R. Chen, B.H. Wang, and T. Zhou.  And the kinds of journals that tend to cite this article the most are undoubtedly physics.  Journals that cite it a moderate amount include computer science, mathematics, and engineering.  Journals that cite it the least include pathology, paleontology, and electrochemistry.  The pattern of citations over time has steadily increased until this year, 2014.  The amount of citations this year extrapolated over the whole 12 month period, though, is still going to be less than 2013.  This may suggest new data has been found to supplant or supercede information in this article.
