Visibilidad y uso de colecciones digitalizadas: Propuesta de un indicador de visibilidad relativa

Abstract

The concepts of visibility and use for digital collections are discussed, and a metric is proposed that relates both of them. Using a web-analytics tool for the data collected from a website, a relative visibility index is suggested, which results from dividing the new users by those returning to the web site. If the number of new users is well above that of the previous ones, that could mean that there are problems of site usability, accessibility, content, etc., because users are not returning. If, on the contrary, the number of previous users is well above that of the new ones, there could be a problem of visibility, as fewer users are arriving to the web site. The metric was developed in a case study involving the log records of the antique book digital collection of the Universidad Complutense of Madrid, from January to June of 2011.
