The author begins his article by stressing the main obstacle facing those who embark upon the task of rebuilding the history of interpreting the quest for sources and particularly secondary sources. He presents a table summarizing research proposals, divided according to possible topics for research, possible sources, methodological procedures, and difficulties the researcher might encounter. The author recommends researchers work in teams, exchanging experiences and findings, and advocates a rightful place for the history of translation and interpreting in training programs.
