Van Tienhoven Travel Award promotes professional growth & development for Mann staff

On Wednesday, November 29, Mann Library staff gathered with members of the van Tienhoven family for an award ceremony made possible through the generosity of the Ans van Tienhoven Memorial Fund. The travel award, founded by Ari and Ans Van Tienhoven 36 years ago and steadfastly enriched by their friends and family over these many years, provides opportunities for professional growth and development for Mann Library staff and librarians. At this year’s ceremony, Carson Williams, Collection Development Librarian and winner of last year’s travel award, presented a report on his trip to the New Mexico State Library’s Tribal Libraries Program. This award enabled Carson to learn about the success of the New Mexico State Library’s efforts in supporting and promoting libraries on tribal reservations, and insights gained have been invaluable for informing Carson’s own work in developing inclusive, accessible collections at Mann Library and the Cornell Library system overall.


The ceremony was also an opportunity to celebrate the winners of next year’s awards and hear about their proposals in more detail. Mann librarians Diana Hackett and Robin Gee received one of the two grants supported by the van Tienhoven Fund. The award will enable them to attend the 2024 Workshop for Instruction in Library Use being held at the Kwantlen Polytechnic University in Vancouver, an institution known for its ground-breaking work in critical and indigenous information literacy. While there, Diana and Robin plan to glean insights and strategies for building the capacity of Mann’s own instruction program for connecting with a diverse student body, increasing students’ confidence in proactive use of library services, and building skills in finding, assessing, and using reliable sources of information.


The second professional development grant made possible by the van Tienhoven Fund has been awarded to multimedia support specialist Ten Van Winkle. Ten will use the award to participate in the 2024 Inclusion, Diversity, Equity, and Accessibility in Libraries & Archives (IDEAL) Conference taking place in Toronto this coming July. Organized around the theme of “Sustainable Resistance and Restoration in Global Communities,” the conference will give Ten the opportunity to explore innovations, strategies and perspectives that will help them take a proactive lead in envisioning, advocating, and realizing inclusive practice in library services in a thoughtful and long-lasting way.


Mann Library thanks the family and friends of Ari and Ans van Tienhoven for their continued support, which has been fundamental to the success of our dedicated staff as we continue to develop inclusive, responsive services and resources for the Cornell community and beyond.

Challenging the Deep: A Ship for Science

Humans have explored only about five per cent of our blue planet’s ocean habitat, but even that bit of progress has much to do with a sea voyage launched one hundred and fifty years ago. On December 21, 1872, the HMS Challenger, a re-tooled British naval ship outfitted with some of the most sophisticated scientific equipment of the times, sailed out of harbor at Portsmouth, England. The Challenger’s circumnavigation of the globe lasted 3-1/2 years and founded oceanography and marine science as formal fields of study.


In celebration of the 150th anniversary of this pioneering voyage, Mann has published “Challenging the Deep,” an online exhibit viewable at, drawing from our own collections and those of Cornell University Library’s Rare and Manuscript Collections, which hold a copy of the Report on the Scientific Results of the Voyage of HMS Challenger, the official collection of the expedition’s scientific work. From professor Leslie Babonis, who teaches the Biodiversity and Biology of the Marine Invertebrates class in Cornell’s Department of Ecology & Evolutionary Biology, we received this feedback when she learned of the new exhibit: “You have no idea how well-timed this is! I was just talking about the HMS Challenger in my lecture about the deep ocean today. I will forward this link to my students so they can get the whole story.” Nice!

Borrow Direct gets an upgrade!

On December 13, the system supporting Borrow Direct will be replaced with a new software called ReShare Returnables developed by Project ReShare, a community of libraries, consortia, software developers, and open-source advocates. 


Launching simultaneously with our Ivy Plus peers, this library-community developed software is meant to advance resource sharing among our partners, and—with continuous improvements over time—offer patrons an improved catalog, more robust searching, and greater access to library materials.


What does this mean for you?

The Borrow Direct service will remain largely the same, and users will continue to enjoy speedy and convenient access to materials from our Ivy Plus partner libraries. There will only be a couple of changes to how you request materials through Borrow Direct:

Cornell University Library’s Evidence Synthesis Service: Innovative Collaborations Amidst a Global Pandemic

2020 has been a year of exciting growth for Cornell University Library’s Evidence Synthesis Service Team. Evidence syntheses, such as systematic reviews, scoping reviews, and other forms of literature synthesis, have emerged as an attractive research alternative to in-person lab and fieldwork for many Cornellians during the pandemic. Working remotely, researchers sought out the expertise of the CUL Evidence Synthesis Team’s six librarians, all trained to provide in-depth guidance and instruction on evidence synthesis methods and their application across disciplines. The era of COVID-19 has also led to new opportunities for our librarians to collaborate on cutting-edge projects, and two major long-term global projects for our team have reached pivotal new phases. We are pleased to share an overview of our accomplishments this year, and to highlight the critical role that librarians play in evidence synthesis work.

This summer, members of Cornell University administration engaged the library’s Evidence Synthesis Team to perform a series of rapid evidence reviews to inform campus reactivation decisions. Drawing from our knowledge of rapid research synthesis methods, we developed eight protocols to outline our approach to search the literature and address research questions identified by Cornell administrators on COVID-19 transmission, surveillance testing and contact tracing. All eight protocols are publicly available on The Open Science Framework in accordance with the defining characteristics of high-quality evidence synthesis: reduced bias, transparency, and reproducibility. This project displays the value that librarians bring to the process of rapid evidence-based decision-making.


Many new studies on COVID-19 are published every day, and researchers are turning to librarians for guidance on methods for effectively synthesizing it. This year, Division of Nutritional Sciences researchers brought on a librarian co-author to their recently published article, Transmission of SARS‐CoV‐2 through breast milk and breastfeeding: a living systematic review. Living systematic review guidelines recommend searching sources at least monthly and making the results of these searches visible to end users within another month. This continuous and consistent approach to literature searching allows for rapid synthesis of fast-publishing studies.


Another exciting project that came to fruition this year is Ceres2030: Sustainable Solutions to End Hunger. Ceres2030 is an international project of 78 researchers from 23 countries that sought the expertise of a global team of librarians who served as co-authors and methodology developers on eight evidence syntheses on topics pertaining to the United Nation’s Sustainable Development Goal 2: Zero Hunger. The evidence syntheses have recently been published in Nature Research as a special collection, and each one features a librarian co-author. Kate Ghezzi-Kopel, Coordinator of the CUL Evidence Synthesis Team, led the global team of 12 librarians involved in this effort. The Ceres2030 librarian team also includes Erin Eldermire, Head of the Flower Sprecher Veterinary library and member of the CUL Evidence Synthesis Service team. Librarian collaboration with researchers on Ceres2030 was critical to the success and eventual publication of this collection of articles that will ultimately influence policy-making decisions.


Although training for medical librarians to support systematic reviews is common, the CUL Evidence Synthesis team has worked over the past few years to expand training opportunities for librarians working on evidence syntheses outside of the health sciences. In partnership with colleagues at the University of Minnesota and Carnegie Mellon University, we received an IMLS grant to provide multiple online trainings for librarians over the next three years. In August 2020, we conducted a pilot of this training to a group of 50 librarian participants who work in fields like life sciences, agriculture, education, business, and others. Recordings from this pilot are freely available, and we look forward to expanding our reach by continuing to train librarians on evidence synthesis methods.

We exist in a world of ever expanding scholarly resources, and librarians are uniquely suited to serve as teachers and research partners when it comes to applying new methods to navigate and synthesize evidence. This year has presented new challenges to researchers, disrupting their usual workflows and forcing them to synthesize rapidly growing bodies of literature quickly. Evidence synthesis is coming into the forefront as an integral library research service during these times, and the CUL Evidence Synthesis Team looks forward to continued engagement with researchers across disciplines to inform high-quality evidence-based decision making in a changing world.
