Presentation by José Antonio Merlo Vega (Universidad de Salamanca = University of Salamanca). Social Entrepreneurship in Action: The Conference for Entrepreneurial Librarians (May 16-17, 2013 / UNC Greensboro). The presentation offers a brief overview of how social entrepreneurship has been practiced in Spain with pertinent examples from libraries, ranging from academic initiatives to social actions in which libraries, especially public ones, are extremely engaged. The Spanish, experiencing so much economic hardship, can demonstrate examples of increased social action from the point of view of mutual support from the library to the community and vice versa. This presentation includes a description of theoretical actions, with examples of actual experiences of libraries that practice social entrepreneurship.
