The digital environment has enabled the creation of new genres and formats that give birth to an array of digital-born sources at the disposal of historians. The traditional digitised sources that refer us to conventional archives are now joined by a series of on-line resources with valuable information on the history and culture of today's world, which should not be ignored by the historiography focused on studying the recent past as well as historiography aiming to analyse the dialogues between past and present. In this document, we have chosen one of those sources, blogs, and we propose methodological guidelines for their analysis. Moreover, a specific analysis is proposed on blogs related to the history and memory of the Spanish Civil War and Franco's regime.
