Why are new journals created? An international analysis of Information and Documentation titles (2013-2018)

espanolSe analiza la creacion o cambios de titulo de las revistas cientificas del area de Informacion y Documentacion (ID) en el periodo de 2013-2018. A partir de un total de 62 revistas identificadas a traves de ISSN Portal y Ulrichsweb se describen: aspectos caracteristicos como paises, idiomas, tipos de editor y modelo de acceso; la difusion en bases de datos bibliograficas, de citas o directorios de revistas; la pervivencia y el volumen de produccion de articulos; numero de citas anual de los articulos en Google Scholar; alcance tematico que declaran los editores; y finalmente, la justificacion que los editores exponen en el cambio de titulo o en la creacion de una nueva revista. Como conclusiones principales respecto a los titulos de nueva creacion, destaca el protagonismo de los editores academicos de sistemas universitarios nacionales en expansion y de los titulos en acceso abierto. En general las nuevas publicaciones generan pocos articulos por ano, tienen poca presencia en bases de datos y reciben pocas citas. Los cambios de titulos se detectan solo en editoriales comerciales. En ambos casos predominan las revistas de alcance tematico general y un numero importante de revistas no justifica su creacion o el cambio de titulo. EnglishThe creation or title changes of scientific journals in the information and documentation (ID) area in the period 2013- 2018 are analyzed. Based on the total of 62 such journals identified through ISSN Portal and Ulrichsweb, the following are described: characteristic aspects such as country, language, type of publisher, and access model; presence in bibliographic databases, citations, or journal directories; survival and volume of articles published; annual number of citations to articles according to Google Scholar; thematic scope declared by the editors; and finally, the justification given by the editors for the change of title or the creation of a new journal. Among the main conclusions regarding newly created titles, the leading role of academic publishers in expanding national university systems and open-access titles stands out. In general, new publications generate few articles per year, have little presence in databases, and receive few citations. Title changes were found only in journals published by commercial publishers. In both cases, journals with a general thematic scope predominate and a significant number of journals did not justify their creation or change of title.
