Considering the several existing studies on history of design that have primary sources of printed materials as the object of their study, many researchers focus their efforts on the systematization and validation of their investigations through appropriate methodological procedures. Within this context, over the years, the Laboratory of Design: History and Typography (LadHT) has built a methodological protocol to standardize and support the different types pf research on magazines, newspapers and other printed materials, carried out by its team of researchers. The first methodological effort regards to the researcher's approach to the socio-historical context of the printed material, including literature review and additional data collection methods, such as interviews. The second effort of the research focuses on the graphic analysis, divided in 7 steps: identification and mapping of collections, photographic record of the collection, organization of the digital collection, creation of the datasheet for the analysis of the printed material, data analysis and discussion of the results (Fonseca et al, 2016).
