    En 2007, los directores, administradores y curadores de colecciones especiales de bibliotecas, archivos y museos se reunieron en un foro sobre cuestiones de digitalización : romper las barreras para discutir cómo avanzar en la digitalización de las fuentes primarias, a la luz de los esfuerzos en ese momento hacia la masiva digitalización de libros. Ahora, diez años después de la primera edición, esa necesidad e importancia sólo ha crecido. Como Merrilee Proffitt escribe en el prólogo: "Más producto, menos proceso fue citado como una inspiración por varios de los oradores de Digitalisation Matters y en la década posterior fue adoptado por la comunidad archivística, desplazando tanto los atrasos como las prácticas archivísticas, incluyendo la descripción. Archivos y salas de lectura de colecciones especiales han cambiado sus políticas sobre el uso de cámaras personales. La comunidad de colecciones especiales ha comenzado a lidiar con los retos especiales de "nacido digital”. Colecciones únicas y distintivas han sido reconocidas como parte importante de una biblioteca de investigación. En medio de este cambio, seguimos buscando cómo podemos digitalizar efectivamente colecciones especiales y mejorar el descubrimiento y el acceso, sin importar el portal o la plataforma y para que estas colecciones estén disponibles en Internet, debemos proporcionarles un paso sin fricción a los entornos que nuestras comunidades buscan "

    Increasing access to special collections

    This presentation extracts the essence of many related efforts to help libraries, archives, and museums increase access to their special collections. The Shifting Gears essay (which was presented to the LIBER conference in 2008) will be used as the launching point. Shifting Gears argued for scaling up the digitization of special collections by thinking in terms of access, instead of preservation (when we are preserving the originals)

    Erway, Ricky. Lasting Impact: Sustainability of Disciplinary Repositories. Dublin, Ohio: OCLC Research (mars 2012) : http://www.oclc.org/research/publications/library/2012/2012-03r.htm Lasting Impact: Sustainability of Disciplinary Repositories offers a quick environmental scan of the repository landscape and then focuses on disciplinary repositories—those subject-based, often researcher-initiated loci for research information. Seven of these repositories are profiled, with a focus on their v..

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    Get PDF
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
