Biodiversity has been a key concept in international conservation since the 1980s, yet historians have paid little attention to its origins. Uncovering its roots in tropical fieldwork and the southward expansion of U.S. empire at the turn of the twentieth century, Megan Raby details how ecologists took advantage of growing U.S. landholdings in the circum-Caribbean by establishing permanent field stations for long-term, basic tropical research. From these outposts of U.S. science, a growing community of American "tropical biologists" developed both the key scientific concepts and the values embedded in the modern discourse of biodiversity. Considering U.S. biological fieldwork from the era of the Spanish-American War through the anticolonial movements of the 1960s and 1970s, this study combines the history of science, environmental history, and the history of U.S.–Caribbean and Latin American relations. In doing so, Raby sheds new light on the origins of contemporary scientific and environmentalist thought and brings to the forefront a surprisingly neglected history of twentieth-century U.S. science and empire.

With new technologies and additional goals driving their institutions, archives are changing drastically. This book shows how the foundations of archival practice can be brought forward to adapt to new environments—while adhering to the key principles of preservation and access. Archives of all types are experiencing a resurgence, evolving to meet new environments (digital and physical) and new priorities. To meet those changes, professional archivist education programs—now one of the more active segments of LIS schools—are proliferating as well. This book identifies core archival theories and approaches and how those interact with major issues and trends in the field. The essays explore the progression of archival thinking today, discussing the nature of archives in light of present-day roles for archivists and archival institutions in the preservation of documentary heritage. Examining new conceptualizations and emerging frameworks through the lenses of core archival practice and theory, the book covers core foundational topics, such as the nature of archives, the ruling concept of provenance, and the principal functions of archivists, discussing each in the context of current and future environments and priorities. Several new essays on topics of central importance not treated in the first edition are included, such as digital preservation and the influence of new technologies on institutional programs that facilitate archival access, advocacy, and outreach; the changing legal context of archives and archival work; and the archival collections of private persons and organizations. Readers will also learn how communities of various kinds intersect with the archival mission and how other disciplines' perspectives on archives can open new avenues.
