Librarians in the Health Sciences Library System at the University of Pittsburgh explored the possibility of developing an electronic reference collection that would replace the print reference collection, thus providing access to these valuable materials to a widely dispersed user population. The librarians evaluated the print reference collection and standard collection development lists as potential benchmarks for the electronic collection, and they determined which books were available in electronic format. They decided that the low availability of electronic versions of titles in each benchmark group rendered the creation of an electronic reference collection using either benchmark impractical. 相似文献

Drawing on concepts rooted in cybernetics and anarchist political theory, this article argues that the shift in Occupy Wall Street from being a physical protest camp in late 2011 to an online movement in 2012 coincided with a shift in social media activity. Analysis of Facebook activity suggests a move from functional to anatomical hierarchy and a corresponding move from many-to-many communication to one-to-many communication. In conclusion, we argue that this development served to undermine the movement's anarchist principles of organization. 相似文献
