The Horn of Africa has an exceptional cultural heritage, starting with its manuscript sources, which are among the most important on the continent. It is a heritage that is rich but scattered throughout the region and not always easily accessible, prompting researchers to rely on cutting-edge technology. Since the 1970s, photography and microfilm have been key for preserving this especially valuable heritage. In the Horn of Africa, the “digital turn” has been the latest development in the close relationship between technology and research. For Ethiopian manuscript studies, the advent of digitization has meant more than simply improving old techniques. A new generation of projects is experimenting with innovative methods of research made possible by digital technology. The purpose is no longer just to provide digital copies of manuscripts but to explore the possibilities that computerization offers to study documents and other historical sources.
Increasingly competitive prices and low operating costs have made the digital revolution attractive even for African institutions, which, in recent years, have sought answers to the pressing needs of preserving and enhancing their historical sources. These technological developments have significantly broadened the range of sources investigated. While important, manuscripts represent only a part of the documentary heritage of the Horn of Africa. Numerous archives and a long-overlooked print culture offer equally interesting access points for studying the region.
The experience gained, though temporally circumscribed, has highlighted a number of more or less predictable problems. The projects to date, although they have often yielded only partial results, have highlighted the wealth of sources still present in the Horn of Africa and the way in which digital technology is making a valuable contribution to their preservation. Access remains perhaps the most critical issue. In the Horn of Africa, as in other African regions, digitization does not necessarily lead to Internet access.

Of central interest here are the historical sources on Islam and Africa, the role and contributions of manuscripts to the narrative, and how the new cyber world has become a domain for those sources as instruments for the generation and utilization of knowledge. Africa came in contact with Islam right from the birth of the faith in the 7th century. Although Judeo-Christian, Late-Antique, and pre-Islamic materials provided the earliest historical sources on Islam and its people, the Qur’an, hadith (statements of the Prophet Muhammad), and the sira/maghāzī (biography/expeditions) were the first original sources on Islamic history on which later writings, including those from Africa, drew.
The manuscript tradition in Islam is as old as the faith itself; it was one of the earliest material sources on Islamic sciences, and in the case of Africa, it provided a treasure trove of materials. At the beginning of the 21st century, the approach to scholarship and utilization of manuscripts changed radically, as digitization, creation of online databases, interconnected portals and links to universal portals, catalogs of manuscripts and published materials, among other innovations, redefined the ways knowledge of Islamic history is generated, accessed, and utilized.

Environmental constraints have large impacts on populations, especially in semi-arid regions such as Africa. Climate and weather have long affected African societies, but unfortunately the traditional climatic record for the continent is relatively short. For that reason, historical information has often been used to reconstruct climate of the past. Sources of historical information include reports and diaries of explorers, settlers, and missionaries; government records; reports of scientific expeditions; and historical geographical and meteorological journals. Local oral tradition is also useful. It is reported in the form of historical chronicles compiled centuries later. References to famine and drought, economic conditions, floods, agriculture, weather events, and the season cycle are examples of useful types of information. Some of the records also include meteorological measurements. More recently chemical and biological information, generally derived from lake cores, has been applied to historical climate reconstruction. Early works provided in most cases qualitative, discontinuous information, such as drought chronologies. However, a statistical method of climate reconstruction applied to a vast collection of historical information and meteorological data allowed for the creation of a two-century, semi-quantitative “precipitation” data set. It consists of annual indices related to rainfall since 1800 for ninety regions of the African continent. This data set has served to illustrate several 19th-century periods of anomalous rainfall conditions that affected nearly the entire continent. An example is widespread aridity during several decades early in that century.
Increasingly, methods not traditionally used by historians are becoming available for the study of African historical geography, landscapes, and environmental change. Starting with an outline of the main determinants of vegetation formations across African landscapes, the article goes on to look at a selection of macro, micro, and modeling methods. Remote sensing allows analysis of land cover change over the past few decades but also shows enduring features useful in interpreting sources describing these landscapes at times long past. Google Earth–type software makes it possible to take a virtual walk through landscapes with key informants in the present day, exploring how the land was used and has changed. Geographical information systems make it possible to collate different spatially explicit types of information, including qualitative data, for quantitative and statistical analysis. At the other end of the scale, pollen, diatoms, foraminifera, and other micro-particles (spicules, phytoliths, cuticles, micro-charcoal) from lake or oceanic sediment cores, and the chemical and isotopic composition of organic remains, all convey information about the environmental context of a site and its surroundings. Carbon isotope or thermoluminescence dating techniques can pinpoint the changes they indicate across potentially very long time spans. Genetic, protein, and other molecular materials may allow precise lineages and migrations to be traced back across very long periods and distances. Finally, modeling makes it possible to use sparse historical and more robust recent data to predict possible pasts in exploratory but evidence-based ways. The disequilibrium debate in drylands illustrates how environmental narratives, strategically used, silence place-based knowledge in ways that science, seeing itself as apolitical, is not well placed to detect.
While there are a handful of defined methods for working with primary historical sources in archaeology, few archaeologists take these as their main points of departure or rely upon them too rigidly. This is to do both with the highly variable nature of the historical and archaeological material available for certain African contexts, and also with how archaeologists conceive of the relationship between these two bodies of evidence: as antagonistic, supplementary, entangled and subjective, mutually creative, and so on. Some methodologies focus on the potentials for consonance and dissonance between written and material sources. Others utilize oral traditions to provide insights into chronology, memory, historical and political dynamics, and the material aspects of these. Still other approaches focus on how historical and archaeological sources offer complementary perspectives on the local and the global, events and processes, and other shifts in scale. While these methods are diverse and contingent, they are united insofar as archaeologists take their cues from objects and from preoccupations with time and space. Archaeologists see their work concerning primary historical sources not as filling in gaps in written records but as addressing the partialities of the records themselves by engaging with an array of complex questions about meaning, authority, and materiality

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.
