The newspaper archives comprise more than 6,000 Basque titles from the late nineteenth century to the present. These include political publications from the 1970s and 80s –many of which are internal publications–, materials published in exile or underground during the Franco era, local publications and publications predating the Spanish Civil War, amongst others. The newspaper archives also include a large number of ephemeral magazines that are very difficult to track down elsewhere. Moreover, many of these magazines are complete series.
