An unusual and varied quantity of publications appeared in Portugal regarding the Centenary of Fatima that was celebrated in 2017. Their common subject is the event of Fatima, although it is looked from different perspectives. It is a set of bibliography constituting a relevant sociocultural and theological observatory of the reality of Fatima. Therefore, our research intends to do a critical screening of such bibliography, which includes books and monographic issues of journals published in Portugal in 2015, 2016 and 2017. This is a period of time we consider reasonable for our work of analysis. We intend to gather, analyze and interpret the different approaches to the reality of Fatima present in this bibliography, in order to get a broad and detailed view of how such reality is pictured. The bibliography includes different literary genres and scientific fields. The research is carried out by an interdisciplinary team where theology, religious studies, sociology, history and literary critics are present.
