See SPOT Play

See SPOT walk, see SPOT climb, see SPOT dance! This spring, we had the opportunity to host a very unusual guest at story time!

Meet SPOT, a four-legged robot created by Boston Dynamics. He lives on Princeton University campus and is part of a course titled “Robots in Human Ecology: A Hands-on Course for Anthropologists, Engineers, and Policymakers.” SPOT arrived with an amazing team of undergraduate handlers, plus plenty of plush toys to share.

We started the program reading Boy + Bot, written by Ame Dyckman and illustrated by Dan Yaccarino (Knopf Books, 2012). The story is about the playful interactions between a boy and a robot, which fit perfectly with SPOT’s dynamic nature. After the book concluded, we had a short, 10 minute design activity in which young future engineers drew their own personal robots, and earned a paw print approval sticker from Team SPOT:

Then it was time for the big show as SPOT entered the gallery!


The students did a fantastic job putting together a demo, answering endless questions from the audience, and just being enthusiastic about sharing what they study. One of my favorite parts was when they demonstrated how SPOT can be programmed to read and follow fiducials, which are basically QR codes representing numbers. SPOT scans the code, finds the number, and then completes a pre-programmed action associated with the number (like moving forward, turning, or extending his arm).

I asked Zoe Rhodes (seen above) what was the best lesson she learned from SPOT this semester. She replied:

“I would say the best lesson I learned from working with SPOT is the importance of making mistakes. We love it when things work out but most of the time we’re dealing with mistakes. But as I’ve worked with SPOT I’ve realized that these mistakes teach us so much more about ourselves and our capabilities than when things go correctly. It sounds a little cliche to say we learn from our mistakes but that’s really what robotics (and most things in life) are about. SPOT may fall down but we pick him right up and try again. In my opinion this makes the end product so much more fulfilling and exciting.”

I posed the same question to Vivian Chen, who added:

“The best lesson I learned from working with SPOT is patience goes a long way when working with robots and new technology!”

It was a truly magical story time, THANK YOU so much to the students and to professors Alexander Glaser and Ryo Morimoto for putting together such a tremendous program!

Happy International Children’s Book Day!

April 2 is not only Hans Christian Andersen’s birthday (happy 219th birthday, Hans!), it’s also International Children’s Book Day! Started in 1967 by the International Board on Books for Young People (IBBY), International Children’s Book Day is dedicated to children’s books and is committed to inspire a love of reading in children around the globe. Schools and libraries are encouraged to host parties or story times, read picture and chapter books, have kids pen their own tales or poems, and overall celebrate a worldwide appreciation of children’s books.

Every year, a National Section of IBBY is nominated to be the sponsor of International Children’s Book Day. The sponsor decides upon a theme, invites a prominent author to write a message, and an illustrator is asked to design an announcement poster. The 2024 international sponsor is Japan!

Japan’s 2024 theme is “Cross the Seas on the Wing of your Imagination.” Author and recipient of the 2018 Hans Christian Andersen Award Eiko Kadono composed a gorgeous letter encouraging children to listen to stories that travel everywhere. Artist Nana Furiya designed the official poster, which whimsically repeats the theme in several different languages under a tall tree filled with book characters.

As Katie was composing this post, she got to thinking…what are our Princeton University Library colleagues’ favorite children’s books? Katie asked them that very question and also asked them to explain why in just one sentence.The book could be a recent read, a beloved title from the past, or a favorite as of today.

The response was tremendous! Our colleagues shared books we remembered reading as a child, titles we had never heard of before, stories we have poured over multiple times, and others we are eager to pick up and read. Here are the favorites, listed in alphabetical order by last name:

“Aside from being beautifully illustrated by Gary White Deer, it’s based on a true story, largely forgotten by most of the world, that unites the disparate parts of my ethnic heritage (which aren’t actually that disparate in the end).”

April Armstrong – Library Collections Specialist V, Mudd Manuscript Library


“I remember reading the Redwall books every chance I could get while on family vacation in Maine circa 1994. Just a totally immersive, absorbing experience.”

Kathleen Brennan – Records Manager


“Not only has it been a joy to read it with both of my kids, but it’s a surprisingly thoughtful little story about childhood anxieties and misunderstandings.”

Tom Bruno – Assistant Director, Content Access


“The art is gorgeous, the book is inclusive, and it’s a great introduction to graphic novels. Plus, the tea dragons are adorable.”

Halle Burns – Research Data Management Specialist


“’Favorite’ does not seem an apt word for describing a story that made a fourth-grade me sob uncontrollably as if in bereavement, but I would not trade the experience of reading “Little Mermaid” for that of reading ten happy-ending stories combined. (HCA’s “Little Mermaid” in Chinese translation by Ye Junjian, not in its Disneyfied version)

Minjie Chen – Metadata Librarian for the Cotsen Children’s Library


“I still quote this book: ‘You get what you get and you don’t get upset.’”

Carolyn Cole – Senior Library Software Engineer


“It illustrates the process of self-discovery.”

Alicia Cozine – Senior Library IT Operations Engineer


“It is a story about not caring what others think or conforming to the role society has written for you. With hard work, persistence and creativity, you can make anything happen – like surrounding yourself with nature, even in the middle of the city.”

Jessica Hoppe Dağcı – Coordinator, Marquand Library Operations and Special Collections


“Her house is upside-down! She’s essentially the neighborhood witch, and I love how all the kids’ commonplace problems manifest in reality.”

Dominique Dixon – Associate Librarian


“Adventures of a worker bee who likes to eat pollen, make sweets, and organize her honey pots.”

Mireille Djenno – Global Special Collections Librarian


“It opens up a good discussion about where our food comes from.”

Ameet Doshi – Head, Stokes Library


Darlene Dreyer – Assistant to the Associate University Librarian


“I read it as an adult and was very moved by it. The description of the family and beautiful young friendship, and the more than devastating ending.”

Rebecca Friedman – Assistant Librarian, Marquand Library


“I love the details in illustrations, and as a young parent I could totally understand Petson’s life with a naughty kitten. I read it in Russian countless times, and it was translated to many languages (English title: Pancakes for Findus).”

Maria Gorbunova – Rare Books Cataloging Librarian


“Besides beings a nice story for children who love animals, I appreciate that it was an early exposure to thinking about ethics in scientific research. It also provided considerate thoughts about the nature of prejudice and touched on environmentalism, so not merely the endearing tale of a motherly mouse seeking to save her sick child from the spring plow, but that was also a lovely aspect of the story.”

Hannah Hadley – Manager, Open Publishing and Repository Services, Library-Data, Research and Teaching Services


Berta Harvey – Library Collections Specialist V, Lewis Science Library


“My children found it so engaging when they were toddlers. It has very expressive pictures and it’s fun to read.”

Anna Headley – Senior Library Software Engineer


“A book of stories and poems, mostly whimsical, always thoughtful, and sometimes melancholical.”

Regine Heberlein – Library IT Data Analyst


“ALL of Freeman’s picture books are beautiful!”

Flora Kim – Metadata Operations Specialist


“It was the first time I’d seen my own love for books and fantasy stories reflected back in a book.”

Morgan Kirkpatrick – Special Collections Project Cataloging Specialist II


“This is a wonderful story about how love and care impact the ways living beings interact with the world – all wrapped up in an adorable story about a family trying to adopt fearsome watchdogs only for each dog to become more of a marshmallow than the last.”

Brittany Norwood – Policy and International Affairs Librarian


“The illustrations are rich; my son and I see something new each time we read it. It’s also a wonderful story about how even the most contentious relationships can be healed!”

Stephanie Oster – Publicity Manager, Library Communications


“My favorite story to read to my kids when they were young.”

Anu Vedantham – Assistant University Librarian for Research, Teaching, and Social Sciences


“Timeless triumph of peace and gentleness over stupidity and aggression. And the cork trees!”

Eric White – Scheide Librarian and Assistant University Librarian for Special Collections



“The book builds self-esteem and kids learn how quiet is a superpower.”

Emily Wild – Chemistry, Geosciences and Environmental Studies Librarian


And how about Katie and Dr. Dana’s books? Since someone already mentioned her favorite picture book (“…but not Ferdinand”), Katie picked Charlotte’s Web by E.B. White “because it’s a beautiful story of unexpected friendship, growth, family, and life’s hardest lesson: learning to let go.”

Katie also reminded me of how she visited Andersen’s home country during her awesome travels in Europe! You can read more about her adventures in this post!

As for me, I picked this Jan Brett classic from my childhood because “I was horse-obsessed.” I spent countless hours reading, studying, and drawing elaborate tributes to this picture book (you can see a delightful story time project we did for it here):

I wanted a horse so so so soooo very bad growing up. Wished for it, dreamed of it, waited for it. It took a couple decades, but my horse FINALLY arrived! My heart runneth over…

Three cheers for International Children’s Book Day everyone! And may all your stories have happy endings!

Stained Glass Stories

Color and concept came together at Stained Glass Stories, our most recent community event! It was connected with our current exhibit, “Once Upon New Times: Reimagining Children’s Classics.” In the exhibit, you’ll find old tales presented in new (and sometimes very unusual) formats. We decided to play with that idea and distill a famous book or character into a single image created in stained glass.

Our event featured six original windows, a mini project for kids, playful light tables, and a little peek at the glass art of the University Chapel. We were also delighted to host artist Karen Caldwell from Sunflower Glass Studio. Read more about Karen (including an interview!) towards the end of the post.

We’ll start with our window gallery, which featured The Wonderful Wizard of Oz, The Very Hungry Caterpillar, Lowly the Worm in his apple car, Chicka Chicka Boom Boom, The Rainbow Fish, and Puss in Boots.

Five of the windows were drawn by talented artist (and Scheide Librarian and Assistant University Librarian for Special Collections) Eric White. The one exception was the Chicka Chicka Boom Boom window. That was me! Since working with real glass was out of the question, we used Gallery Glass brand non-toxic window paint ($20 for a pack of 8 basic colors) and imitation non-toxic leading ($14 a bottle). Instead of glass sheets, we used acrylic, which was lighter weight and much safer. A 12″ x 16″ acrylic sheet runs about $5 each on Amazon.

To create the windows, we enlarged Eric’s original drawings, printed them on 11″ x 17″ paper, then traced them onto the acrylic with Sharpies. Next came the window paint, and after that dried, the leading. Here you can see the windows in progress…

Another terrific thing about using acrylic is that you can drill holes in it. On event day, we used self-adhesive hooks, fishing line, and S-hooks to hang the windows.

A few words about the window paint and leading. Yes, window paint is technically paint, but it is thin and sometimes requires multiple layers. We found it works best if you skip brushes all together and squeeze the paint directly onto the surface in a thick layer. And the imitation leading can be fairly viscous. So get ready for some serious squeezing.

Because of cost and mess, we couldn’t give kids individual bottles of window paint. So we came up with a plan for our mini window project that worked really well. At the event, kids received a 5×7 foam carrying/drying tray (125 for $19 on Amazon), a 5×7 acrylic window (20 for $13 on Amazon), a small color palette (8 for $20 on Amazon), six Qtip “paintbrushes,” and a color menu.

The paper menu correlated with an acrylic menu we hung by the window, so kids could see how the colors appear when they are dry. At the event, they could choose up to 6 colors.

The color menus further correlated with paint bottle holders I made out of box tops and paper cups. This helped me and Katie locate colors fast, and also kept the bottles upright.

Kids then took everything to worktables where Sharpies were waiting in bins. They used the Sharpies to draw on the acrylic, colored it in with the paint, then took it to the drying tables. Our system totally worked…we had ZERO paint spills or accidents and the kids were really delighted with the little color palettes.

For caregivers who didn’t want to navigate paint, we made small copies of four of the custom windows, and had a coloring table with washable markers.

But in an interesting twist, some folks brought the coloring sheets over to the worktables and traced them onto their little windows! Below you can see a gallery of some window art, including tributes to Eric White’s fabulous creations!

We couldn’t have a stained glass event without mentioning the beautiful Princeton University Chapel, which is not only one of the largest campus chapels in the world, it also houses some truly stunning stain glass windows. Katie put together a display honoring “The Poetry Window,” by Rowan and Irene LeCompte, which features the likenesses of Virgil, Dante, Chaucer, Shakespeare, Donne, Milton, Blake, Eliot, and Dickinson!

The surprise runaway event hit, however, were the light tables. These were 3 LED light tracing pads we purchased on Amazon. We bought large 11″ x 16″ pads, which cost $40 each, but there are definitely smaller cheaper one available. The light pads were paired with translucent shapes and tiles (about $9 – $13 a set, depending on the style), Katie also spotted a super cool pack of 12 transparent geodes (Amazon, $25).

I know the figures I quoted above can be budget-busting, but we did purchase the light table supplies for use at future events and programs. We’ve already rolled them out at our baby social hour, and plan to bring them to community events as well. EVERYONE loves these. Even adults!

The grand finale at the event was Karen Caldwell from Sunflower Glass Studio. She generously displayed her works, tools, did live demos, and chatted about glass techniques from the Middle Ages to modern day! Below is an interview with her, interspersed with photos of her event display.

Hi Karen! Please tell us about yourself!

I have been working in glass for almost 50 years, creating my business Sunflower Glass Studio in 1978. I came to my love of prisms and beveled glass as a young child, amazed of the rainbows passing through beveled glass in the movie Pollyanna. When I started designing glass in the early 80’s, one of the first investments we did was to purchase a beveling machine, to create spectacular windows.

How did you come to work with stained glass?

Through my college studies of art and horticulture, I worked in several different areas of employment, always doing work with my hands. It was a logical move when I secured a job assembling large Tiffany-style hanging shades, and then started free-lancing my designs back to the company. Within a few years, my partner, and then husband Geoff stated working with me in the glass studio. Throughout the decades, we adapt styles, techniques and skills to doing many types of glass fabrication, in the cold and warm methods of glass (stained glass, beveled glass, painted glass and fused glass).

How many step are involved in the creation of a window?

There are generally four to five distinct steps in creating a window: designing; selection of glass; cutting each piece of glass; soldering or leading the pieces together; final finishing steps.

What is the most difficult part of your craft?

The most difficult part of creating a window is the designing. The balance of a piece, and the color combinations are all the most important parts in the piece. From there it is mainly a matter of creating a stained glass puzzle into a window.

Do you have a favorite piece, and why?

My favorite form of glass is my newest art form – fused glass. I love working on my flower designs and trying to create a two-dimensional flower that appears the be
3-D. The fused glass botanicals that I create gives me must more freedom in the design aspect, compared to stained glass designs. Since I make each botanicals part in thin wafers, then compose the design and through a long kiln-firing to bond the pieces to a base glass, I do not need to be concerned with the background pieces. In stained glass, I always need to make sure the positive and negative pieces are cut-able. In fused glass, I just need to make sure the windows are balanced and flow.


Many thanks to artists Karen Caldwell and Eric White for contributing your incredible skills to the event. We appreciate you so much!
