Archives used in Africanist historical research include those of the colonial state, postcolonial national archives, missionary archives, personal papers, political party archives, and the archives of corporations and international agencies involved in African affairs. Africanists historians generally accept that these archives are not transparent renditions of the past; they represent and even reproduce power relations related to colonialism and its legacies. Nonetheless, careful readings have enabled Africanist historians to understand the structural order and logic these archives (the archival grain), and thus demonstrate colonial (or other) power relations implicated in the collections. Reading archives against the grain can also reveal alternative voices and agents, however. Even as discussions of archival methodologies have been limited, archives have remained crucial sources for key trends in Africanist historical writing, including the representation of colonial hegemonies as well as African voice and agency. To advance such readings, Africanist historians develop post-positivist readings of archives that appreciate silences, dissonances, and conflicts within archives and documentation. Through a process of archival fieldwork, including a careful combing of archives, reading of files, and transcribing of select documents, historians have become adept at appreciating the grain of archives and reading the archive against this grain. The digitization of archives and digital research methods, including electronic search engines, full-text searches, online archives, and digital photography, challenge aspects of traditional archival fieldwork, holding benefits and potential setbacks for the critical appreciation of archival documentation. These challenges have sharpened with the changing role of physical documentation along with an increase in smaller archives that enable serendipitous and hodgepodge archival investigations.
