Since first issuing in March 1877, the Boletín de la Institución Libre de Enseñanza (BILE) has been one of the leading Spanish journals on the subject of experimental and social sciences, as well as education. It reviewed the contents of various major European and American publications, including regular collaborations with foreign authors, Spanish institutions, and their international colleagues, working to establish a respectable web of sources. From the creation of the weather service in Japan, until the first reports of radioactivity, automotives, and wireless telephone, the BILE was one of the prime sources of knowledge as to what was happening throughout the world.
