For more information on state-wide emergency information:Florence’s projected path as of Monday, September 10, 2018. Help for Cultural Institutions
The National Heritage Responders (NHR) – formerly the American Institute for Conservation – Collections Emergency Response Team (AIC-CERT) – responds to the needs of cultural institutions during emergencies and disasters through coordinated efforts with first responders, state agencies, vendors and the public. Volunteers can provide advice and referrals by phone at 202.661.8068. Requests for onsite assistance will be forwarded by the volunteer to the NHR Coordinator and Emergency Programs Coordinator for response. Less urgent questions can also be answered by emailing email@example.com.
Cultural institutions in FEMA-designated disaster areas of Texas, Louisiana, Florida, and other impacted states and U.S. territories can apply immediately for NEH Chairman’s Emergency Grants of up to $30,000 to preserve documents, books, photographs, art works, historical objects, sculptures, and structures damaged by the hurricane and subsequent flooding. Applications for emergency grants are available here (Word Document).
If you are ready to start recovery you can use the Emergency Response and Salvage Wheel ro recover collections. The Wheel is also available in an app on both Android and Apple devices. Many other useful apps are out there to help you find information or organize a response.
Local and state organizations such as state archives, museums, university libraries, etc., will have experts on staff that can help answer collection emergency questions. Many states also have state-wide preservation groups with experts who can help (e.g. the North Carolina Preservation Consortium, LYRASIS, Texas Library Association). LRYASIS Performing Arts Readiness has experts to help performing arts organizations respond to disasters.
September is National Preparedness Month. Even if your institution was not affected by recent storms, now is a good time to review your current disaster plans and training. The Alliance for Response links cultural heritage and emergency response representatives. There may already be a local AFR network near you or you could consider forming one.

In conservation there are so many different materials to learn about and each one has specific and unique properties that can impact how we approach a treatment. It’s impossible to know everything about every material. So any opportunity to cross-train or broaden a skillset can allow a conservator to better manage a wider range of objects.
About a year ago I had the opportunity to attend Sheila Siegler’s Parchment Conservation workshop offered by the International Preservation Studies Center. It was a weeklong intensive on the history and preparation of parchment, parchment identification, and various treatment techniques.A sample of true parchment (left) versus ‘parchment paper’ (right) through the microscope
We often get items made from parchment in our lab and I was especially interested in learning more about treatment methods for this finicky material. In the workshop I learned new methods for flattening and drying and came back to the lab eager to put those new skills to use.Stretching a parchment document after humidification
Last week I had the opportunity to pass on some of those skills to North Carolina Museum of History Object Conservator Jennifer French. She had a parchment document in her collection in need of flattening and was looking for advice on how best to manage it. Our lab has previously collaborated with NC Museum of History when Textile Conservator Paige Myers visited our library to provide advice about a silk banner in our collection and we were happy to return the favor. I took a field trip over to Jenifer’s lab and we got to work.Photo credit: Jennifer French
The document was very cockled and uneven making it difficult to handle and house. Using a vapor chamber we created a high humidity environment to soften the parchment and ease out some of those wrinkles. While the parchment humidified we prepared our materials for drying. The humidification was a slow process so we had plenty of time to talk shop, sharing tips and tricks for an assortment of other treatments.Humidification chamber in action
Once the parchment had been humidified for many hours the larger wrinkles were relaxed and it was much flatter already. We transferred the document to dry between felts and blotters under plenty of weight (those heavy conservation books come in handy).
A little over a week later Jennifer checked on the document and found it had flattened considerably. It still has some areas of minor undulation but it’s so much better, and more than good enough to be handled and rehoused.Photo credit: Jennifer French
For now the parchment will stay under weights until Jennifer and I meet up again to create an enclosure that will ensure the parchment stays safe and flat in the museum’s storage.
This kind of cross-institutional collaboration on projects was not only great fun but a rare opportunity for hands on information sharing and skill building. As conservators we get by with a little help from our friends.
Late last week our lab hosted a 3-day workshop, taught by Jennifer McGlinchey Sexton, on Tools and Techniques for UV / Visible Fluorescence Documentation. Colleagues from libraries and museums around the country joined three DUL staff members to learn about the necessary equipment and to develop practical skills in capturing UV/visible images for use in conservation.
A great deal of the discussion centered around equipment. We looked at several kinds of UVA lamps that are currently on the market and talked about the filtering necessary on both lamps and cameras to reduce infrared and visible light. We also went over some methods for testing the quality of the lamp.
Capturing UV/visible images can be challenging and while standards have been widely adopted in recent years for conservation imaging under normal illumination, the same is not so true for UV documentation. Jennifer described several workflows for setting the white balance and selecting the best camera exposure settings using either home-made or standardized fluorescent color targets.
We had converted both our normal photo-doc space and the “dirty room” (our mold remediation and chemical storage space) into imaging work spaces, so the workshop participants were able to break up into two groups and practice. It was very useful to have two spaces and enough equipment that everyone could try the process several times and ask questions.
This workshop was a great opportunity to learn exactly how to add UV/visible to a conservation program’s documentation capabilities. It gave the participants a grounding in both the functionality of the equipment and a framework for consistently producing high quality images. For the Duke library staff who participated, this workshop also added some perspective to the work we have done in the last year or so with Multispectral Imaging.
We are so thankful to Jennifer McGlinchey Sexton for teaching, to Tess Bronwyn Hamilton for assisting, and to FAIC for sponsoring such a great experience!
Today is the last day for Phebe Pankey, our HBCU Library Alliance/University of Delaware Winterthur intern. The past two months have flown by. We have thrown a whole semester’s worth (maybe more) of information at Phebe in eight weeks. She has learned a lot of new skills and has applied those skills to projects in the lab.
Some of the skills she has learned include:
- Minor book repairs in the circulating collections
- Minor paper repairs in support of the Section A digitization project
- Custom enclosures including 4-flap boxes, corrugated clasmshell boxes, and CoLibri covers
- Humidification and flattening of rolled plans from the Sarah P. Duke Gardens drawings and designs collection
- Condition survey of the Bobbye S. Ortiz Papers
- Mold removal
- Photographic and written conservation documentation
- Selection for conservation for general and special collections
- Disaster planning and recovery of bound books
- Environmental monitoring
Henry taught Phebe how to sew a Coptic binding. Isn’t her first book beautiful? Phebe completed 494 repairs and custom enclosures during her internship. She completed work for the general collections including Perkins Library, Music Library, and Lilly Library. She also completed 119 repairs for Rubenstein Library in support of our digitization project to scan the collections in “Section A.”
A big shout out to Kelly Wooten, Research Services and Collection Development Librarian in the Sallie Bingham Center, for hosting a show and tell of artist books. These really made an impression on Phebe, who is an art major. It’s great to see someone get inspired by our collections and our people.
We also scheduled tours all over the library and across the greater Raleigh-Durham-Greensboro areas. Some of these were:
- Rubenstein Library stacks tour
- Duke Libraries Technical Services tour
- Duke Libraries Library Service Center tour
- UNC Chapel Hill special and circulating conservation labs
- NC State Archives conservation lab
- Etherington Conservation Services
- HF Group (commercial bindery)
- NC State University Preservation Department
As we wrapped up this week we were lucky to have lunch with Miranda Clinton who is a student at NC Central University. She interned at the Library of Congress. We asked her to lunch to hear about her experience. Sounds like she had an amazing time there.
If you want to look back at some of the other work Phebe did, here are the blog posts:
Everyone in the lab helped Phebe learn new skills. Thanks to Erin Hammeke, Rachel Penniman, Mary Yordy, and Sara Neel for being so giving of your time and expertise. Thanks to everyone at Duke Libraries for being supportive of Phebe and generous with your time. Thank you to all the organizations that gave us tours. It’s always educational to see other labs and how they compare to ours. Thanks to the Gladys Krieble Delmas Foundation for awarding us a grant to help support this internship. And a big thank you to all the student interns who made the first year of this program successful. We can’t wait to see where you all go next.
It’s that time of year again when we report our annual statistics to our administration. We thought we would share these with you, too.
1,093 Book Repairs (down 38% from last year)
1,066 Pamphlets (down 38%)
1,392 Flat Paper (down 87%)
5,975 Protective Enclosures (down 15%)
66 Disaster recovery
8 Exhibit mounts (down 64%)
746 hours of time in support of exhibits (includes meetings, treatment, installation, etc.) (up 452%)
1,002 items repaired for digital projects (down 90%)
38% of total work was for Special Collections
62% of total work was for Circulating Collections
74% of work was Level 1 [less than 15 minutes to complete]
23% of work was Level 2 [15 minutes – 2 hours to complete]
3% of work was Level 3 [more than 2 hours to complete]
Looking at the three year trend you can see the impact of two things. First, we had a steep decline in paper repairs because last fiscal year we were working on a mass digitization preparation project (dark red line). Those numbers skewed our stats for FY2017. In February, Tedd Anderson resigned as our conservation technician, and Mary Yordy reduced her hours. You can see their impact on the stats. Tedd did the majority of custom enclosures (green line) for Rubenstein Library. And both Tedd and Mary repair general collections materials (light red line). We had a huge exhibit project this fiscal year that included a lot of complicated and time consuming repairs. You see a marked decrease in the percentage overall of items repaired for Rubenstein Library, but there was a marked increase in length of time we spent on those repairs. So the percentage is down, but the number of Level 3 repairs are up.
Not Everything Is A Statistic
- Conservation Services was reorganized in January 2018. We now report to Dracine Hodges, AUL for Technical Services.
- We welcomed Sara Neel, our new Senior Conservation Technician.
- We hosted 11 tours of the lab totaling 86 people
- We presented 16 Care and Handling Training sessions to DUL staff
- We hosted our first HBCU Library Alliance/University of Delaware-Winterthur conservation intern
- We hosted two Girl Scout bookbinding-badge workshops
- We did cool things like helping to CT scan the ivory manikins , continued to investigate the use of Multi Spectral Imaging for conservation treatment, and used textile conservation techniques to repair a book.
- We responded to a few disasters in Perkins and Lilly libraries.
We hope you enjoy looking back at the year that was FY2018 as much as we did. We can’t wait to see what FY2019 brings.
As custodians of cultural heritage, we are always trying to learn more about the collections within our care. We see many leather bindings come through the lab for treatment that have been decorated in some way. Tooling of leather bindings can be quite complex, and it can be difficult to get a sense of the skill or time required to create those kinds of decorations without trying it for oneself. One afternoon this week, we all gathered together to learn some of the basic techniques for blind and gold tooling by hand.Henry talks through the process and demonstrates tooling.
At the most basic level, tooling is accomplished by pressing a heated metal tool into a dampened leather surface. Only a few pieces of equipment are required: brass tools set in wooden handles, a heat source, a cooling pad, a sponge, and suede for cleaning the face of the tool. The process is not complicated, but there are a lot of variables to consider and it takes a great deal of practice to get the right results.Phebe and Sara tooling plaquettes.
After a short demonstration of making simple lines, everyone got to try it themselves on plaquettes (small pieces of binder’s board, covered in vegetable tanned goatskin). Most of us drew inspiration from the common decorative styles from the 18th century book trade, making concentric panel designs with tooled flowers at the corners.
With some blind lines in place, we each tried some gilding. A shellac-based solution called “fixor” is painted into the tooled lines and allowed to dry. Then, working on a leather cushion, sheets of gold leaf are cut down to size.Phebe cuts gold leaf to size for gilding.
If all the previous steps in the process were done correctly, the gold sticks in place and looks very clear and bright. If it doesn’t go so well – then you just start over and try it again.
Becoming proficient at finishing takes many thousands of hours of practice, so we couldn’t really develop much skill in just a few hours. But there is something valuable in just trying a craft for oneself. Not only can you learn more about the kinds of marks or characteristic changes that occur when it all goes wrong, but you develop a deeper appreciation for craft done well.
We are getting the first large collections that have been selected for freezing into our freezer. We are following the National Park Service’s guidelines for packaging photographic materials for freezing.
Lucy Vanderkamp worked with us to wrap these boxes of negatives. We got better and faster at wrapping as we went along. By about box ten we felt like experts.
If you are unfamiliar with the NPS “Conserve-O-Gram” series, there is an awesome amount of information there. Check them out.
As part of her 8 week summer internship, we’ve been trying to give Phebe some experience in the different kinds of collections care activities that Conservation Services regularly undertakes. This week, we took a break from enclosures and treatments to talk about collection assessment.
The Rubenstein Library holds a collection of papers from Bobbye S. Ortiz, which includes several folders of eye-catching 20th century activism posters from around the world. This collection has seen increased use recently from undergraduate classes and exhibits. As parts of the collection have been called down to the reading room, we have become aware of some condition and housing issues. This seemed like a good opportunity to both introduce condition assessments and prioritize the needs of an increasingly popular set of library materials.
After talking through the kinds of data that we would need to collect in order to develop treatment workflows for the collection, we built an assessment tool using Google Forms. The form feeds data into a shared spreadsheet with each submission. We have found entering information into a form to be a little more user-friendly for an item level assessment than trying to directly fill in a row on a spreadsheet. It also allows us to easily make use of controlled vocabulary, so that the data can be effectively sorted later.
With our assessment instrument in-hand, we gave it a test run through 15 or so of the posters in the collection. As part of this process, we could go through each question in-depth, and show specific examples of object characteristics that we intended to capture with the form. Pretty quickly we realized that we needed to add a field or change the format of fields, but the tool makes that very easy to do.
There are over 100 posters in this collection, but Phebe has been making good progress over the last couple of days. When the assessment is complete, we can coordinate with the curators and Rubenstein staff to plan systematic rehousing or conservation treatment for the items that need some sort of intervention.
We collectively realized yesterday that we are close to hitting the half-way point of our first HBCU Library Alliance Summer Internship. How did that happen so quickly? I guess time flies when you are having fun!
In the last few weeks, we have continued introducing our intern, Phebe, to common materials and repair techniques that we use to maintain library and archives collections. For example, she has been contributing to the digitization prep workflow by dry cleaning manuscripts and performing simple paper mends with Japanese paper and wheat starch paste, as well as heat-activated, pre-coated Japanese papers that we make in-house.
We have spent some time outside of the lab, touring different library departments in order to show how conservation supports wider library initiatives. Touring the Digital Production Center and speaking with the staff has helped to put the digitization prep workflow into better context. Winston Atkins, our Preservation Officer, also came by this week to give an overview of collections care activities, like environmental monitoring, integrated pest management, and disaster planning and response.Sara Neel, Phebe Pankey, and Conservator Rebecca Smyrl examine an artist book at Wilson Library, UNC-Chapel Hill.
With so many great cultural institutions in the Triangle, we have been able to introduce Phebe and our new staff member Sara to a number of other conservators in the area. In addition to visiting the special collections conservation lab at UNC-Chapel Hill, we organized an informal conservator meet up here in Durham. Our colleagues in the area work with very different collections, such as museum objects, paintings, and musical instruments. We don’t get to see them as much as we would like, so this was a great excuse for everyone to gather together.
Please help us welcome our newest staff member, Sara Neel. Sara recently graduated from the University of Kansas with a degree in Art History and a minor in French (which has already come in very handy). Sara worked in the UK Libraries Conservation Lab from 2015 until graduation this year. She has studied abroad in Italy and France;, and recently gave a paper at the Missouri Western State University & The Albrect-Kemper Museum of Art Second Annual Undergraduate Art History Symposium titled “The Assembly of the Tejaprabha Buddha: Removal, Restoration, and Religious Reduction.”
So far this week she has gotten her bench in order, helped edit some lab manual documents, learned to make corrugated “pizza-box” enclosures, and discovered that the Parking Office is really far away from our building. We are so happy she is here!
This week the Conservation Services Department was joined by our first ever HBCU Library Alliance Summer intern, Phebe Pankey! Duke is one of five library conservation labs participating in this program to host an eight-week internship in preservation and conservation this summer.
Phebe is a junior at Winston Salem State University and has been involved in libraries most of her life through volunteering and community activities. She is excited to learn more about conservation and this internship is a way to continue developing and expanding her library skills.
Phebe has jumped right into the lab workflows, learning to construct some of the quicker enclosures like CoLibri sleeves and 4-flap boxes. She has also been gaining experience with basic paper treatments, like humidification and flattening.Phebe works with Conservation Specialist Rachel Penniman on humidification of paper.
At the conclusion of the eight weeks, interns are expected to take some of the skills they have learned back to their home institution to implement a library preservation project, building on the success of their summer experiences with an opportunity to perform meaningful work preserving significant HBCU library collections at their institution.
These internships would not have been possible without the help of the Samuel H. Kress Foundation, the University of Delaware College of Arts and Science, the Department of Art Conservation at the University of Delaware, and the Winterthur Museum, Garden, and Library (DE). Thanks also to Debbie Hess Norris and Melissa Tedone at the University of Delaware.
We will continue sharing more about this internship as it progresses, but for now: Welcome to Duke, Phebe!
Duke Today has a new story out about the collaborative work that staff from Conservation, the Rubenstein Library History of Medicine Collection, and the Shared Materials Instrumentation Lab are doing to house, scan, and eventually 3-D print our ivory manikins. Check out the story here. And watch this very cool video of the process.
We had some torrential rain in Durham last night and early this morning staff at Lilly Library on East Campus reported water on the floor in the basement level. Facilities and Conservation Services quickly sprang into action to assess and respond to the needs of the affected collections.
Luckily no books were affected. Only some VHS tape cases and paperwork on a desk got wet, so we were able to set them out on tables with box fans and oscillating fans to dry.
A crew from AfterDisaster also quickly arrived and began removing water from the carpets, opening the bases of walls to allow the sheetrock to dry, and setting up dehumidifiers. One of the dangers to book and paper collections after flooding is elevated relative humidity (RH) for long periods of time. This can promote mold growth, so their efforts will ensure that the RH returns to normal levels quickly.
This is the second basement water event we have had in as many months, but in both cases we followed our disaster plan and our collections came through relatively unscathed. It’s great to work with such a great team!
Today we hosted a delightful group of grad students from a class that Liz Milewicz, Head of Digital Scholarship Services, is working with. They declared Conservation to be “The Best Tour Ever.” We kind of agree. Here we are looking at Kenneth Arrow’s Nobel Prize medal. We recently had the preparators from the Nasher Museum here to fit the Nobel medal for a custom display mount. We know this medal will get a lot of use so we are having a special display mount made for it. The Nobel Prize is something almost everyone has heard about but rarely do you get a chance to see one up close. It’s a special object to have in the lab for show-and-tell.
It’s Preservation Week! Each day we are showing examples of how the conservation department supports the library and its mission. We’ve seen Mary getting items back into circulation, Beth in an important meeting, Rachel showing off a Nobel prize, and Erin undoing some worm’s evil work. In our final post for the week, we will talk about how Conservation supports training and the digitization of collections .Undergraduate student Helen Lee applies heat-activated repair material to mend some manuscripts.
Collection materials are constantly being imaged over at the Digital Production Center to provide greater access to scholars around the world. All those materials undergo careful review by our staff before going under the camera, and some items need stabilizing repairs in order to be handled and imaged safely. The sheer quantity of requested material can easily overwhelm our full-time staff, so sometimes our part-time student employees can help with the quicker repairs. Helen Lee (pictured above) has been working in the lab for the past three years and has been trained in several kinds of paper repairs ideal for digitization prep. Today, she is using strips of pre-coated Japanese paper, which we make in the lab, to mend tears on archival material. She uses a small heated tacking iron through a barrier of silicone-coated paper to apply the repair strips.
Helen is graduating this semester and we are so sad to see her go! But it is rewarding to see students head off on new adventures and hopefully some of the preservation training she received here will come in handy along the way.
Happy Preservation Week!
It’s Preservation Week! Each day this week we are telling a short story about how the conservation department supports the library and its mission. We’ve seen Mary repairing circulating collection materials, Beth representing in the board rooms, and Rachel working on custom mounts. Today we will take a peek at something a little more… chewed.
Erin Hammeke, Senior Conservator for Special Collections, is currently working on an 18th century Spanish history of North America from the Rubenstein collection, which was badly eaten by insects at some point before it was acquired by the library.
The insect damage is so extensive in places that the book is very difficult to handle without causing further damage. In order to make this item accessible to researchers, Erin is applying strong, but reversible, mends of Japanese paper to infill each one of the losses. The color of the repair blends nicely with the original paper, so that it does not distract so much from the text.
The conservation treatment of this item will take a considerable amount of time, but it will ensure that a valuable resource is made available to patrons for many years to come. With all the requests for special collections items, either by scholars in the reading room, for our exhibitions, or for digitization, we work closely with our colleagues in Special Collections to prioritize treatment and make treatment decisions.
It’s Preservation Week! This week, we are looking at the daily life of a conservation department and the work we each do in support of the library and its mission. On Monday, Mary was repairing a book with very cool end papers. On Tuesday, Beth was in a meeting (surprise!).
Sometimes you need to bring in expertise when faced with a particular challenge. Rachel is working with Brad Johnson and Patrick Krivacka from the Nasher Museum of Art to build a custom mount for Kenneth Arrow’s Nobel Prize medal. Today was the medal’s first fitting. They also discussed the finish for the stand and came to agreement on the height of the frame.(L to R) Rachel Penniman, Brad Johnson, and Patrick Krivacka discuss the fit of the display stand.
Kenneth Arrow was an economist, professor, and Nobel laureate. Arrow’s career is especially distinguished by his contributions to the theory of social choice, including his book Social Choice and Individual Values, published in 1951, and his contributions to general equilibrium theory. For these achievements, Professor Arrow has been awarded the Johns Bates Clark Medal (1957) and the Nobel Memorial Prize in Economics (1972), which he shared with Professor Sir John Hicks.
We are very excited that we will have a custom-fit stand so that the Nobel medal can be displayed in classes, show and tells, and exhibits. Thanks Patrick and Brad!
It’s Preservation Week! This week, we are looking at the daily life of a conservation department and the work we each do in support of the library and its mission. Yesterday we saw Mary in repairing a book with very cool end papers.
As a department head my job is to make sure we have the budgetary and human resources that we need to do our work, advocate for my staff and department, and make sure our priorities fit into the strategic direction of the library. To that end, I attend a lot of meetings.Technical Services department head meeting.
Duke Libraries has a culture of collaboration, so we do a lot of talking with each other. My standing meetings include departmental and individual staff meetings; Technical Services Department Head meetings; meetings with my supervisor; the monthly all-library staff meeting; the Multi-spectral Imaging team meeting; quarterly division meetings; and meetings with other department heads outside of Technical Services usually over lunch or coffee. Then there are special meetings that are called around projects or initiatives, budget setting, and other administrative duties. Then there are the meetings that happen on the fly at the bus stop, in the hallway, or in the cafe line.
By attending these meetings I am gathering the information I need for the department to be successful, I’m building relationships across the library, and I am also finding out what is happening in other departments that might impact our workflow. I know for some people all these meetings sounds like torture, but I rather enjoy getting together with colleagues to think about our collaborative future. And sometimes you get doughnuts.
It’s Preservation Week! In an effort to raise awareness of the need for preservation of all kinds, every day this week we will highlight one of the many ways our staff support collections at Duke University Libraries. Our first stop is the circulating collection.
This visual album about Barneys New York shows a common problem with modern art books: the flimsy case construction of the binding just doesn’t stand up to the weight of the textblock. While it is down here in the lab, Mary will repair the rear hinge of the book, rejoining the text to the binding and allowing it to function again for many more circulations.
The publisher of this item really went all out with the endpapers and “chameleon” metallic edge treatment!
The post Preservation Week: Maintaining the Circulating Collection appeared first on Preservation Underground.
Conservator Erin Hammeke has been working with History of Medicine Curator, Rachel Ingold and SMIF Research and Development Engineer, Justin Gladman to facilitate the scanning of our 22 ivory manikins using a High Resolution X-ray Computed Tomography Scanner (Micro CT scanner). These high resolution 3-D scans allow us to see internal components of the manikins, thoroughly document them and their component parts, and also to create 3D printed models to allow for unfettered access and handling of surrogate manikins by patrons. So far, we have imaged over half of the collection of 22 manikins to date over 7 imaging sessions.
Conservation’s support for this project has been a team effort. First we researched the safety of the process for ivory and component parts. Then we thought through the logistics of ensuring their physical safety and security during imaging. Over the past year, Conservation Specialist, Rachel Penniman has been carefully boxing each of the manikins in terrific custom padded artifact boxes (see Quick Pic: Boxing Near-Naked Ladies) to assist with their safe transport to the SMIF facility on campus. After transport to SMIF, Erin unpacks the manikins and removes their parts before securely wrapping them in low density material to support the manikin during the 20-30 minute scan. Thanks to Beth for sewing custom foam supports for this project!
Smaller, removable internal organs are imaged in separate scans to enable an adjustment to the scanning resolution and isolation of the component parts in the digital scan and 3D print.
This photos shows some of the ways in which Erin strapped and supported a manikin with a loose arm during scanning, as well as still images from the scan that show internal metal fasteners and repairs that are not visible upon external examination.
And here is an example of a 3D print of one of our solid manikins showing fantastic detail.
Keep an eye out for a more in depth Duke News story about the project by science writer Robin Smith, PhD.
