Systematically retrieving research in the digital age: Case study on the topic of social networking sites and young people’s mental health

Online information seeking has become normative practice among both academics and the general population. This study appraised the performance of eight databases to retrieve research pertaining to the influence of social networking sites on the mental health of young people. A total of 43 empirical studies on young people’s use of social networking sites and the mental health implications were retrieved. Scopus and SSCI had the highest sensitivity with PsycINFO having the highest precision. Effective searching requires large
generic databases, supplemented by subject-specific catalogues. The methodology developed here may provide inexperienced searchers, such as undergraduate students, with a framework to define a realistic scale of searching to undertake for a particular literature review or similar project.

Antonio y Gabriel de Sancha, libreros de la Ilustración, y sus relaciones comerciales con Inglaterra

In this article we take as our point of departure the booksellers' catalogues printed by the Sanchas during the reigns of Charles III and Charles IV, as well as the catalogues issued by their London correspondents the booksellers Thomas Payne and Benjamin White. We contextualize the business relationship which developed between the Sanchas and the London booksellers as a direct result of Gabriel de Sancha's visit to London in the Summer of 1784. This study highlights the significance of a parallel offer of recently published books in English and Spanish in some of the most renowned bookshops in Madrid and London between the mid 1780s and the years immediately before the Peninsular War, a circumstance that no doubt stimulated curiosity on both sides and sped up the transfert culturel between both countries. Notwithstanding their business and private troubles, Antonio and Gabriel de Sancha, self-reliant entrepreneurs and cultural intermediaries, were able to establish a dynamic book trade flow which did not imply the subordination of Spain to England.
