Character Trouble with John Doris 

Human character has less of an influence on action than both philosophical theory and our everyday experiences would have us think, according to John M. Doris, the Peter L. Dyson Professor of Ethics in Organizations and Life and professor in the Sage School of Philosophy­. A leading proponent of interdisciplinary approaches to moral psychology exploring questions of character, virtue, and agency since the 1990’s, Doris has now collected over 20 years of his work into Character Trouble: Undisciplined Essays on Moral Agency and Personality (Oxford University Press, 2022). In this book talk, Doris will reflect on this collection, as well as discuss recent developments in understanding of moral cognition and behavior, and the moral psychology of character.

The Nature of Data with Jenny Goldstein 

It is not possible to fully understand current global environmental politics and responses to environmental challenges without understanding the role of data platforms, devices, standards, and institutions, according to Jenny Goldstein, assistant professor in Global Development. In her book talk, Goldstein discusses her new book, The Nature of Data: Infrastructures, Environments, Politics (University of Nebraska Press, 2022), coedited with Eric Nost, assistant professor at the University of Guelph, which brings together scholars from geography, anthropology, science and technology studies, and ecology to explore these connections, and reveal how environmental politics are waged in the digital realm.

Draping for Apparel Design with Susan Ashdown 

The apparel industry, though driven by fashion and expected to embrace transformation, is often resistant to change in its technologies and vision, according to Susan P. Ashdown, Professor Emerita in Human Centered Design in the College of Human Ecology. This attitude has also been apparent in patternmaking textbooks used in apparel programs, but in editing the 4th edition of Draping for Apparel Design (Fairchild Books, 2022) Ashdown transformed this text from a ‘how-to’ book suited to a 1950s classroom to a modern book with an inclusive vocabulary, as well as methods and topics directed to the students who will lead the apparel industry in the future.

Weeds of the Northeast with Antonio DiTommaso 

Identifying your local weeds can be relevant to everyone from home gardeners to landscapers, pest management specialists, allergy sufferers, and foragers of all kinds. In this book talk, Antonio DiTommaso, professor and Chair of the School of Integrative Plant Science Soil and Crop Sciences Section, will discuss Weeds of the Northeast, 2nd edition (Cornell University Press, 2023) a fully updated edition of the best-selling original full of lavish illustrations and detailed descriptions to aid in the identification of more than 500 common and economically important weeds in a region reaching as far south as North Carolina, as far north as Canada, and as far west as Wisconsin. Weeds of the Northeast is also a handy yet comprehensive reference for those aspects of weed biology and ecology which are most important to weed management.

Welcome (back) students!

The Spring 2023 semester is off to a snowy start, and we’re happy to welcome Cornell students back to the library! You may have noticed some changes since the end of last year, including the large area cordoned off on the 1st floor. Please be mindful and avoid the atrium area as you enter and exit the building. We have a construction project beginning in February that we hope will only last a couple months, so please pardon our mess while we make some much needed improvements! 


A few other things to remember as you get back into the semester routine:

COMING SOON: the new CALS Zone. located in Mann Rm 112 off the lobby. Starting in February, in addition to being our contactless pickup area and a 24/7 study space, this will also be a dedicated space for CALS advising help. Watch our website for an opening announcement in the coming weeks!

New Library Website for the New Year!

Cornell University Library is starting the new year off with an exciting announcement: we have a new website! Our newly redesign site has all the great features of our previous website – such as our search box for the library catalog front and center on the home page – along with some great new functionality to make navigation easier and more efficient for our users. Some notable features include:

Have feedback to share with our development team? The link to our feedback form can be found at the top of all the webpages on the new Library site. To the many users who have already shared feedback with us or participated in our testing throughout the development process, we thank you for helping us design a site that works for you.

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:

Mann @ 70 Scavenger Hunt

Mann Library is celebrating 70 years on the Cornell Ag Quad and we want you to feel part of that history!


On the first three floors of the library, you will find stations/small tables with information about what the library looked like in its early decades and how it has evolved over the years. Go to the stations to find the answers to the following four questions.


  1. What year was the renovation of the original Mann Library building complete?
  2. What caused the fire (epic!) in the Mann Library building in 1964?
  3. What 1950’s technology allowed communication between library staff working at the circulation desk and staff working in the closed library stacks?
  4. Mann Library opened Cornell University’s first public computer lab in the early 1980’s. Who was it named after?

Submit your answers in the online entry form here: If you get them all correct, you’ll be notified via email to come select a prize at the Mann Help Desk. The prize line-up includes posters or note card packets with images from our special collections, Mann travel mugs (while supplies last!), and other swag. One entry per person. The scavenger hunt ends November 29.


Happy hunting — and best of luck as you wrap up the semester and head into exams!
