Crowds and psychology | A video of a mass prank / experiment conducted in NY Central Station; the link to Stanley Milgram's work (of “small world” or “six degrees of separation” fame) leads to a pay-per-view article, but the usual sources offer all the introductory information you will ever need, and a few good articles on psychologist's Judith Kleinfeld's site. But, whatever you may think of the validity of Milgram's thesis, Google makes a small world in its search results and offers a wonderful link to an article by Kathryn James (Reference Librarian, Beinecke Rare Book and Manuscript Library, Yale University) on Six Degrees of Information Seeking: Stanley Milgram and the Small World of the Library (the link is a Digital Objct Link to an Elsevier article through Science Direct; original in the The Journal of Academic Librarianship, 32:5, 2006, 527–532). This came to me only days after a discussion on the merits of displaying the latest issues of Humanities journals in hardcopy vs. relying on electronic posting of contents and abstracts: easy to see how chance discoveries of relevance from disparate fields may be fostered or hindered by the notification mechanisms.
