Halloween is just around the corner, and the skeletons have come out of the closet. From front yards reimagined as graveyards to bone-chilling retail displays and party backdrops rattling with more than a few spare ribs, bones are on display to awaken the Halloween spirit and set a ghoulish mood to the delight of trick-or-treaters everywhere.

The modern-day Halloween is derived from the ancient Celtic festival of Samhain. With the Celtic new year celebrated on November 1, October 31 marked the end of summer and the harvest and the beginning of the cold, dark winter. Samhain, celebrated the evening of October 31, was believed to be a time when the boundary between the worlds of life and death were blurred, allowing the ghosts of the dead to return (History.com 2019).

Over time, Halloween has evolved into the costume-wearing, trick-or-treating holiday that it is today, but the season’s association with death has remained, evidenced by the proliferation of ghosts and skeletons intertwined with modern-day celebrations.

Embracing the Halloween season’s bony obsession, this month’s book of the month is one devoted to the skeleton — Osteographia (1733), which has been described as “one of the most important and beautiful books in the British anatomical tradition” (Neher 2010, 517). This work is freely available in BHL thanks to the Library and Archives of the Natural History Museum in London.

The family Syrphidae, commonly called hover flies or flower flies, include some 6,000 living species. As “one of the most abundant groups of flower visiting insects”, with adults of most species feeding almost exclusively on pollen and nectar or honeydew, these flies are among the most important pollinators, both for wild plants and numerous crops.

The multi-volume Diptères exotiques nouveaux ou peu connus (1838-[43]) by Justin Macquart contains the first descriptions of numerous Diptera species, including many members of the Syrphidae. Systema Dipterorum, the biosystematic database of world Diptera, attributes 430 Syrphidae names to Macquart.

“Macquart wrote so many early Syrphidae genus and species descriptions that it’s almost impossible to write a syrphid taxonomic paper without referencing this title at some point,” explains Dr. Andrew D. Young.

Young is a University of California, Davis postdoc, working out of the California Department of Food and Agriculture Plant Pest Diagnostics Center, where he specializes in Diptera taxonomy and phylogenetics. Although he studies Tephritidae (fruit flies) in his current position, most of Young’s entomological training has been focused on Syrphidae. While Macquart’s monographic series is an essential resource for this group, it’s not easy to come by.

“Each volume is several hundred pages, and was published in the mid 1800s, so hardcopies are not particularly easy to get ahold of,” explains Young. “Most of the time when you do find a hardcopy, it’s one that’s been photocopied so many times it’s barely legible.”

Fortunately, Diptères exotiques nouveaux ou peu connus is freely available on the Biodiversity Heritage Library (BHL).

Twitter is a popular communication channel amongst the scientific community. Scientists use the platform to communicate with colleagues and share their research findings with both other scientists and the public.

Twitter may also be a valuable source of data for researchers. For example, ecologists from the University of Gloucestershire found that “Twitter-mined” data is useful for phenological studies, such as winged-ant emergence or the appearance of house spiders in the fall.

Twitter conversations can also spark unexpected discoveries. For example, a recent @BioDivLibrary Twitter conversation helped uncover a connection between the scientific literature and a museum’s collections.

Two new fossil fly species have been named in honor of the Smithsonian Libraries and the Biodiversity Heritage Library. Sylvicola silibrarius Greenwalt, 2019 and Kishenehnoasilus bhl Dikow, 2019 have been described from specimens collected from the 46-million-year-old Kishenehn Formation of northwestern Montana. The species were published last week in the open access journal Palaeontologia Electronica.

Charles Darwin’s Library is a digital edition and virtual reconstruction of the surviving books owned by Charles Darwin. Produced as a collaboration between BHL, Cambridge University Library, the Library & Archives of the Natural History Museum in London, and the Darwin Manuscripts Project, the collection draws on original copies and surrogates from other libraries and includes over 500 of the 1,480 books in Darwin’s library. Notably, these books are complemented with fully-indexed transcriptions of Darwin’s annotations.

Charles Darwin’s Library is particularly meaningful to Dr. B. Ricardo Brown, Professor of Social Science and Cultural Studies at the Pratt Institute. Brown has devoted years of research to Darwin and the impact of his evolutionary theories on debates around monogenetic vs. polygenetic human origins. Brown’s 2010 book, Until Darwin: Science, Human Variety and the Origin of Race, explores the complex web of factors that influenced these debates from the 17th-19th centuries and the impact of the publication of On the Origin of Species on this scientific discourse.

Brown spent nearly 10 years researching this book. Today, BHL’s open access collections offer researchers considerable time-savings.

“I am sure that if I had the kind of access to texts that BHL now provides researchers, I could have reduced the research time for Until Darwin in half,” muses Brown.

The Biodiversity Heritage Library (BHL) has added functionality to allow BHL Partners to upload transcriptions in place of the automatically-generated OCR (Optical Character Recognition) for archival materials digitized in BHL. This functionality supports transcriptions generated as part of Partner crowdsourcing projects on Smithsonian Transcription Center, DigiVol, and From the Page.
