The Foreword to this special issue of Itinerario describes the historical questions that inspired the Global Sea Routes project, from which the essays in the issue derive. It then illustrates the particular sources used in the project, namely logbooks, specifically those of the English East India Company, whose characteristics and interpretation problems are briefly presented. Then, it illustrates the digital tools used in the analysis of those sources and to obtain the digital graphic and cartographic representation of the research results; and finally, it introduces each individual essay contained in the issue.

Research into maritime history using digital tools is a growing field, with projects that in recent years have focused on the role of sea spaces in the dynamics of globalisation on an economic and juridical level as well as on a cultural level, with respect to the circulation of knowledge. In this introduction to our special issue, we offer some historiographical observations on the codification of knowledge in seafaring practice, emphasising how the use of digital tools to process and represent primary sources may encourage historians to formulate new questions about the relationship between European culture and the sea during the early modern age. In order to present the articles in this issue and the original contribution they make to the field, we also focus on the historical and cultural significance and methodological challenges posed by primary sources such as logbooks. We illustrate how the analysis of logbooks in a digital environment such as Global Sea Routes (GSR), a project conceived and coordinated by Guido Abbattista, can foster a better understanding of the role of routine navigations in early commercial globalisation.

This article describes the methods and arguments of Hearing the Americas, a digital public history project that illuminates the history of popular music and the recording industry from 1890 to 1925. We argue that the use of digital tools allows the website to integrate sound directly into writing on music and thereby explicate a series of historical arguments. The article examines three arguments advanced by Hearing the Americas, showing in each case how digital tools generate new insights. The first case uses mapping to reveal some of the specific ways in which the economic and social context of Jim Crow shaped the experiences of Black performers; the second integrates sound and text to reveal the origins of certain blues conventions in the racist stereotypes of minstrel shows; and the final case uses digital tools to argue that the marketing strategies of the recording industry throughout the Americas helped produce a key shift in patterns of globalization.

During the early 1970s, the Sahel suffered from drought and famine. Previous research has emphasized how these factors weakened West African states. The drought, however, provided an opportunity for a transnational river organization in the Senegal River basin (the OMVS) to obtain financing for an integrated development program. Wall shows how the OMVS leveraged concern about famine to obtain funding. She uses digital text analysis to demonstrate institutional priorities shifting to focus on agriculture. This combination of document analysis with digital methods demonstrates how famine strengthened a multi-state organization, requiring a revision of how this event affected African political capacity.

Biographies constitute the main historical record of China. The China Biographical Database (CBDB) is an important project that tackles this vast biographical material with digital technologies. With both online and offline versions, CBDB is meant to be useful for statistical, social network, and spatial analysis, as well as serving as biographical reference. Through the wide range of data it collects through mining historical texts and reference sources, CBDB offers multiple ways to examine the lives of past groups and individuals in Chinese history. The use of CBDB data for prosopographical and other types of analysis has generated important work that interprets Chinese history in new ways, and has also fostered new forms of digital humanities collaborations. This article introduces the history of the CBDB project and its methods for populating its biographical data. It also presents the ways that historians and other scholars could utilize its data for research and teaching.
