The North American Sylva is a beautiful scientifically and historically-significant work. Authored by François-André Michaux, it is the first American silva – a descriptive flora of forest trees. Published originally in French in 1810, the first English version appeared in 1817, and it was further enhanced with supplementary volumes by Thomas Nuttall in the 1840s.

Did someone say Spring?!

In Ottawa, we start to see the Canada Geese returning to their summer nesting grounds around this time of year. Large flocks of them fly overhead in the same v-shaped formations we saw months ago when they left in the late fall.​

Aren’t migratory birds fascinating? Along with so many other Canadian bird species.

Birds of Canada by Percy Algernon Taverner remains one of the best accounts of the kinds of birds that occur in Canada. And the first thirty-six pages holds just the right amount of information to open the science of ornithology to bird lovers, yet still enough information to satisfy research needs.​

The Arnold Arboretum of Harvard University has contributed a century of their publications to BHL as a part of the Expanding Access to Biodiversity Literature project, including: Bulletin of Popular Information (1915-1940) and Arnoldia (1942-2016). Nancy Rose, an arborist with a background in woody plant research and horticulture extension, served as Arnoldia’s editor from 2008 to February 2018. Before retiring, she shared with us some reflections on the their contributions to BHL.

During the summer of 2016, I had the privilege of working on a collection development project for the Biodiversity Heritage Library (BHL) for a Professional Development Internship with Jacqueline Chapman at Smithsonian Libraries. My task was to refine a collection assessment methodology for BHL using both taxonomic and bibliographic analyses.

BHL will be unavailable due to network maintenance starting 0900 GMT on Monday March 5, 2018. This downtime may last up to a few hours. During this time you may access our collection via the Internet Archive. Thank you for your patience.

In the middle of the Cold War, the Smithsonian Institution embarked on the Pacific Ocean Biological Survey Program (POBSP) to survey U.S. territory islands and atolls dotting the central Pacific Ocean. From 1963 to 1969, researchers sought to inventory the plants and animals present on the islands, observe seasonal variations in numbers and reproduction, and the distribution of pelagic birds. Over the course of the survey, researchers observed approximately 150,000 pelagic birds at sea, banded 1,800,000 birds, and surveyed the flora and fauna of the islands, the most comprehensive study at the time. An incredible amount of data was collected during the POBSP, drastically increasing information available about the ecology of the small islands.
