In recent years, research in the historical-educational field has greatly expanded the spectrum of sources used to reconstruct the history of teaching in an effort to gain a deeper understanding of the true scholastic experience. To this end, the authors believe that the examination of teachers’ personal archives and libraries can provide a new contribution to the progress of studies in this sector. Proffering an initial overview of the results of their investigation, still scarce and in a certain sense entirely new to this field of research, the authors have focused on a very unique case study: the documentary and bibliographic archives of primary school teacher Maria Riccini (Ancona 1892- 1975), preserved at the University of Macerata’s Centre for documentation and research on the history of schoolbooks and children’s literature. The purpose of this paper is to reconstruct, for the first time, the experiential journey of a specific teacher through a series of indisputably significant sources: her personal library, consisting of training texts (pedagogical and didactic manuals, disciplinary manuals from the normal school, etc.), texts adopted for teaching and continuing education (school textbooks and reading books for primary school students, teaching journals, and cultural magazines); her personal archives, containing documents related to her own didactic work (teaching programs, notes and summaries used for conducting lessons, notebooks with newspaper clippings collected for educational purposes, etc.), and materials produced by the students (dictated texts, essays, exercises, drawings, etc.). The novelty of the approach adopted in analysing this variegated set of sources consists in having cross-referenced and re-read them within the framework of a historical reconstruction that aims to insert the human and professional history of Riccini into the historical-cultural and historical-scholastic context in which she lived and worked, intertwining her life’s work with the significant eras that defined the nation’s history, from fascism to the post-World War II period. It is, therefore, a «story seen from within», which does not speak of an abstract category of teachers, but rather of a specific teacher, her contribution and her direct educational impact, in order to provide a new historiographical perspective on the history of teaching.
