This article aims to clarify the concept of community literacy and produce a definition in order to better understand its fields of study and action. The methodology is based on a literature search including a bibliometric analysis and a systematic review of the literature conducted on a corpus of Anglo-American and Spanish-language texts. The results of this research reveal that the concept of community literacy is based on a series of constitutive dimensions: difference and diversity, locality, critical and ethical agency, delineation and continuum of literacies. This comprehensive review of the literature and these findings will enrich theoretical and practical approaches while fostering the engagement of different actors in community literacy.
